pH stands for Power of Hydrogen. If you still remember your chemistry concepts this post will surely take you down the memory lane. Who can forget the mysticism of color changing property of the litmus paper? Wasn’t it a marvel to see the paper turn Pink from Blue when you squeezed a lemon on it! If your memory evades you or if you had bunked that particular class, read on.
RO Water pH- First Know the Basics
Role of pH In Nature
To put forth this concept in simple terms, we’ll explain it in layman terms. The pH is measured as a numerical scale running from 0 – 14. All things which taste sour are acidic and have pH level less than 7. Chemicals tasting bitter are Basic and have pH ranging from >7 to 14. The strongest acid will have its pH very near to 0. The strongest Base would have its pH touching 14. Base chemicals which are soluble in Water are called Alkalis.
Our Nature maintains a very delicate pH balance. Even the pH of the soil in a region governs what type of vegetation grows well there. Pure water has a pH of 7. Distilled water is considered to be the purest form of water. The rain water falling directly from the sky is distilled water too. This is not to suggest you can drink the rain falling after a long gap. You should not forget the polluted atmosphere the rain is falling through. Hence, once there have many rainy spells then only rain water can be deemed potable.
What pH of Water is Safe For Drinking?
As mentioned above the purest form of water i.e distilled water has a pH of 7. You can consume water with pH ranging from 6.5 to 8.5. As a rule of thumb prefer alkaline water as much as possible. There are water purifiers which dispense alkaline water after correcting the pH. Havells Max Alkaline 7-Liter RO+UV Water Purifier is one such appliance.
Acidic Water and Its Impact On Health
You must have heard of a term- Acid Rain. Due to the intense pollution plaguing our skies the water droplets falling through it becomes Acidic. Poisonous gases like sulphur dioxide, nitrogen dioxide react with water to turn it acidic. Acidic water is in no way beneficial for health. Acidic water flowing through metal pipes cause its corrosion. In some cases heavy metal impurities like Lead can make their way into our stomachs. In a way you can remove the acidity of water if you remove the dissolved metals. Ion-exchangers come handy to this end.
Alkaline Water and Its Impact on Health
Areas where water is salty is often called Hard water and is typically Alkaline. Mountain regions where water is high in dissolved salts of sodium, calcium and magnesium is alkaline. Hard water tastes awful and is often not pleasantly palatable. RO water purifiers with Ion exchange mechanisms can correct the pH levels.
Hard Water causes greenish scaling of bathroom fittings and rusting of steel, screws and other iron surfaces. Who would not have experienced the difficulty in washing clothes or hands in hard water? Clothes get uneven discoloration and soaps do not lather easily.
The key knowledge shared in this post is to avoid drinking acidic water at all costs. For once alkaline water is tolerable but limit the alkalinity as well. Use good quality Water RO and Mineralisers. RO removes the dissolved metals salts along with heavy metal impurities like Arsenic, Lead or Mercury. The Mineraliser replenishes the removed salts sans the harmful ones. Read our Best RO Water Purifier Review for such products which help you drink better water. There are good Non-electric gravity based water purifiers too. A PH meter can come handy to measure RO water PH for assurance.
