Correcting water pH level

Add potassium carbonate (K2CO3) to water. This will increase pH of water as calcium can increase hardness if calcium carbonate is added. Sodium carbonate could be challenging for sodium conscious people. If solutions of potassium carbonate mixed with sodium hypochlorite (K2CO3 + NaOCl) are added to water, this will increase pH and will disinfect water as well because the pH of these chemicals are from pH 10 – 11. If the pH rises too high it can be lowered with acetic acid (white vinegar) to adjust it. Dilute solutions of hydrochloric acid and sulphuric acid can also be used to lower the pH. However, the safe method is to adjust pH with acetic acid. The safe pH for drinking water is from pH 6.0 to 9.0.
