what is the ph of water


Water, composed of hydrogen and oxygen, requires specific components and conditions to be considered suitable for human consumption. Among these requirements is the pH of water, which must fall within certain values for people to drink it.

Fortunately, the pH of water can be measured and adjusted if it is not within established standards. So, let’s understand what water pH is, when it is suitable for drinking, and other important details to consider.


pH is a measure of the alkalinity or acidity of an aqueous solution in general terms. In water, pH determines the concentration of hydrogen ions, hence the acronym: potential of hydrogen ions. pH is measured using a logarithmic scale ranging from 0 to 14, where each point represents a tenfold change in acidity. In other words, a pH of 1 is ten times more acidic than a pH of 2.


The water pH test can determine the alkalinity or acidity of water, with the neutral value being 7 on the scale. To get an idea of the pH of other common liquids, distilled pure water has a pH of 7, lemon juice is around 1, and bleach is approximately 13.


Maintaining stable water pH ensures the safety of its consumption and prevents potential serious problems. Altering water pH can change the concentration of other substances, making it toxic. For example, a decrease in pH can increase the amount of soluble mercury in water. This also affects organisms and microorganisms living in water, as many chemical reactions require a specific pH for survival and growth.


Various methods exist to analyze the pH of water and aqueous liquids in general:

  • pH paper: The most common method involves using special strips that change color when in contact with the liquid, thanks to their vegetable dye.
  • pH test: A glass electrode containing an acidic solution is inserted into the water to generate an electric force between the water and the acid, which can be measured. This generated force is the pH measurement.
  • Other tools for measuring pH: Analytical colorimeters based on an ink indicator that changes color according to the detected pH.


Changes in pH can occur for various reasons, broadly categorized into two groups:

  • Chemical buffering capacity: Chemical buffers that neutralize acids, such as CO2 from the air dissolving in water and neutralizing minerals from rocks.
  • Entry of basic or acidic substances: Changes in temperature, human activity, pollution, etc.


The main problem with maladjusted pH is that water may become toxic, as seen in the example of high mercury presence. This can lead to issues in the body, with water being more harmful the more acidic its pH is. Gastrointestinal symptoms are the first to appear, but heavy metal poisoning is more challenging to detect and more severe.


The optimal pH of water for human consumption, i.e., drinking water, can vary between 6.5 and 9.5. In Spain, water consumed through taps typically has a pH around 7.7, making it practically neutral. In places where tap water is more alkaline, systems can be installed to treat water and adjust pH, such as reverse osmosis (reverse osmosis water has a pH of approximately 6.5). Well water for drinking should have pH levels between 7 and 8.5. Although frequent checks are conducted, official bodies ensure that consumed water falls within acceptable values, both for pH and other components.

Benefits of Alkaline Water

benefits of alkaline water
benefits of alkaline water

Alkaline water is water in which oxygen molecules outnumber hydrogen molecules and it carries an extra electron. The benefits of alkaline water come in the form of antioxidant bubbles known as hydroxide ions. These ions work to remove free radicals from the blood, reducing oxidation and aging, which are two factors in many types of cancer, as reported by the non-profit organization BeatCancer.com.

Over time, factors such as poor diet, stress, and smoking increase the acidity of the blood, making the body more susceptible to diseases like cancer. Cancer cells struggle to thrive in an alkaline environment, as alkaline water creates an inhospitable setting for their growth.

Here is a summary of the benefits provided by alkaline water produced by Apollotek International products:

  • Helps fight cancer
  • Prevents the development of diabetes
  • Can help you look younger
  • Nourishes brain, nerve, and muscle cells
  • Can aid in weight loss
  • Strengthens the immune system
  • Acts as a powerful antioxidant


Benefits of Salt-Free Water Softeners There are two types of water softeners:

salt-based and salt-free. A salt-based water softener gives you a “spotless” feeling in the shower, enhances soap lathering, and results in brighter and more vibrant colors in your clothes. On the other hand, salt-free systems also reduce scale buildup, provide brighter colors in clothing, and softer skin using a healthier method. The main advantage of a salt-free water softening system is the ability to soften water without adding sodium, making it a healthier option for both the heart and the environment.

In summary, the Benefits of Alkaline Water include:

  • Cleaner and shinier silverware, glassware, mirrors, tiles, cars, and faucets
  • Soft and clean skin and hair
  • Reduced soap scum buildup, easier household cleaning, and reduced housework
  • Less soap and shampoo needed due to abundant lathering with soft water and soap
  • Softer clothes without hard minerals trapped in the fabric, resulting in longer-lasting fabrics and whiter whites without the dinginess caused by hard water
  • Extends the life of all water appliances, such as coffee makers, ice machines, dishwashers, water heaters, and laundry equipment
  • Saves money on monthly energy costs and prevents damage to appliances

How does a Water Conditioner Work? The Problem: As water travels underground to the surface, it picks up soluble matter along the way. This water is filled with minerals, such as calcium and manganese, which significantly affect how we use it in our homes. The presence of these minerals and their interaction in water according to its use makes the water hard.

One effect of hard water is that soaps and detergents lose their effectiveness. Instead of fully dissolving, soap mixes with minerals, forming a coagulated soap curd. More soap is required because less dissolves in hard water. This sticky, insoluble curd remains deposited on our skin, preventing proper cleaning. Washed hair may appear dull and lifeless.

Laundry is not much better with hard water. Soap curd may be present even in your clothes while washing in your automatic machine. This can result in dirt being trapped in fibers, leaving the fabric stiff and rough. Besides affecting the washing process, insoluble soap deposits leave stains on everything you wash, from dishes to the family car. A layer of soap scum slowly accumulates in your bath and shower.

Another reason to be concerned about hard water is its effect on the plumbing system. Calcium and magnesium deposits build up in the pipes, reducing flow in water faucets and other appliances. In water heaters, these minerals create scale buildup, reducing efficiency and the life of the water heater.



The Solution: The solution to this problem is to remove calcium and magnesium from the water. While chemical treatments exist for this purpose, the most common method is a water softener.

The most common water softener is a mechanical device installed in the water supply of your home. All water softeners operate on the same principle: they exchange harmful minerals, such as calcium and magnesium, and replace them with sodium and potassium. This process is known as ion exchange.

The heart of a water softener is a mineral tank filled with small beads of polystyrene, also known as resin or zeolite, which carry a negative charge.

Calcium and magnesium in the water have positive charges. This means that these minerals will adhere to the beads as hard water passes through the mineral tank. Sodium ions also have positive charges, although not as strong as the charge on calcium and magnesium. When a highly concentrated saline solution flows through a tank that already has beads saturated with calcium and magnesium, the volume of sodium ions is sufficient to expel the calcium and magnesium ions from the beads. Water softeners have a separate brine tank that uses common salt to create this saline solution.

In normal operation, hard water moves into the mineral tank, and calcium and magnesium ions move onto the beads, replacing the sodium ions. The sodium ions enter the water. Once the beads are saturated with calcium and magnesium, the unit enters a 3-phase regeneration cycle. First, the backwash phase reverses the water flow to remove dirt from the tank. In the recharge phase, the concentrated salt solution, rich in sodium, is transported from the brine tank and flows through the mineral tank. Sodium accumulates on the beads, replacing calcium and magnesium, which are flushed down the drain. Once this phase is complete, the mineral tank is rinsed of excess saline solution and refilled.
