Answer :
pHs of less than 7 point out acidity, whereas a pH of larger than 7 shows a base.
pH is actually a measure of the relative quantity of free hydrogen and hydroxyl ions in the water. Water that has extra free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic.
What is a high pH?
High pH. A waterbody is considered to have a high pH if pH exceeds 9 for prolonged durations or with excessive frequency. High pH is less common than low pH as a candidate cause, because anthropogenic sources are acidic greater frequently than basic.
What increases the pH of water?
Soda ash (sodium carbonate) and sodium hydroxide raise the pH of water to near neutral when injected into a water system. Unlike neutralizing filters, they do no longer motive hardness problems in dealt with water. Injection systems are a point-of-entry system.
