pH Level in Drinking Water, Acceptable Levels | Reviewed

The changing color of litmus paper is one of the most amazing or magical aspects of science. We all must have been amazed at the way that blue litmus paper can turn red in acidic solutions, and then blue when it is dipped into alkaline solutions.

If I remember correctly, I also did these tricks such as cutting a lemon using a knife that was dipped in a litmus solution. These were our first encounters with pH.

pH Level in Drinking Water Acceptable Levels

What is pH?

pH is an indicator of acidity or alkalinity in elementary terms. A solution with a pH value below 7 is considered acidic and a pH value above 7 is considered alkaline. Pure water is a neutrals liquid, with a pH value of 7.

The pH value of the colas that you consume regularly is around 2.5. This means that they are very acidic. This is why you should avoid drinking too many carbonated drinks. Apple juice also has a pH value of 3. The pH value of orange juice is 3.5 and milk 6.2 respectively. All of these liquids contain acid.

You can now see the alkaline solutions. Baking soda has a pH value of 8.5, soapy waters 10, and bleach 12.

What does pH stand for in water?

As we have already seen, pure water has a pH value of 7. Pure water is tasteless, odorless, and colorless. To make water taste good, you need to add salts and minerals.

The pH value of water is affected by the addition of minerals or salts. According to the BIS, water should be between 6.5 and 8.5 pH. Groundwater has a pH value between 6 and 8.

The pH value has an impact on the taste of water

Drinking water that is not within the BIS range can be harmful to your health. Let’s see what happens if water is consumed outside of this range.

Acidic water

Acidic water is water with a pH below 7. You will notice a bitter taste in water with pH levels below 6. Acids can corrode metals. Acidic water can cause metal impurities to build up in the water supply.

This is why you must raise the pH level of the water by eliminating metal impurities. This water can be handled best by RO water purifier systems.

Alkaline water

BIS also states that water with a pH greater than 8.5 is unacceptable. This is called “toxic water”.Extremely difficult nature.

Consuming alkaline water with a pH greater than 8.5 can have a significant effect on your kitchen and heating coils. It is not pleasant tasting.

All over the country, municipalities use chlorine to neutralize alkaline water. You will need to use more chlorine if the water is harder. This can have a negative impact on your health.

You can use this information to your advantage. RO water purifiers and Ion Exchange water purifiers are available to neutralize alkaline water.

Water softeners can also be used to soften water, particularly if it does not contain high levels of TDS. This is a more effective way to neutralize the water than using an RO water purifier.

Are rainwater and its benefits good for your health?

It all depends on how and when you drink it. Rainwater can be quite acidic, which can surprise some people. Rainwater disintegrates the carbon dioxide, sulfates, and nitrates in the air as it descends towards you.

Rainwater pH values can be measured in areas with high levels of industrial and vehicular pollution. The pH value is between 4 and 5.

You can also harvest rainwater and store it in a tank. Rainwater harvesting increases the pH value and makes it more palatable. It is best to purify rainwater at home with a RO water purifier.

Is it possible to alter the pH value of water so that it is suitable for drinking?

The pH value is only one factor that affects water’s suitability. Remember that your stomach produces hydrochloric acid (pH values of around 1 to 3.5). Your body can also digest acidic substances.

Is it unable to digest carbonated drinks? Every day, we have coffee. Coffee has a pH value of 5.5. Vinegar with a pH value of 2.8 is also available in our food.

The pH value can make a significant difference in water’s taste. An RO water purifier of high quality can provide water with a pH value between 7 and 8. The TDS controllers and the Mineralisers replenish essential minerals and salts, thereby increasing pH to between 7.5-8.5.

What are the consequences of drinking acidic water?

Acidic water can cause metal and pipe corrosion. Acidic water can corrode pipes and metals. This can have a negative impact on your health. These metal deposits build up in our bodies and can cause severe harm.

Alkaline water has an alkaline effect

Alkaline water can also be called hard water. As such, hard water does not cause any harm to our bodies. The water is not good tasting. This can make your coffee bitter. Salt deposits can form on bathroom fittings and vessels from hard water. It can be difficult to lather soaps. This can lead to the formation of insoluble precipitates.

How can you test the pH of water?

There are many pH level testers available on the market. These simple digital devices can quickly determine the pH level of your water.


This discussion reveals that water should be consumed within the acceptable BIS range of 6.5 to 8.5. To make water more palatable, you can use water purifiers and Ion exchange appliances. Our bodies can maintain pH equilibrium by themselves. It is not affected by water intake.
