Answer :
pH of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
pH is virtually 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 greater free hydroxyl ions is basic.
What is a high pH?
High pH. A waterbody is considered to have a excessive pH if pH exceeds 9 for extended intervals or with excessive frequency. High pH is much less frequent than low pH as a candidate cause, due to the fact anthropogenic sources are acidic more frequently than basic.
What increases the pH of water?
Soda ash (sodium carbonate) and sodium hydroxide increase the pH of water to near neutral when injected into a water system. Unlike neutralizing filters, they do no longer motive hardness troubles in dealt with water. Injection structures are a point-of-entry system.
