Explanation:
Detailed explanation-1: -The range goes from 0-14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
Detailed explanation-2: -Strong bases have very high pH values, usually about 12 to 14. Well-known examples of strong bases include caustic soda or sodium hydroxide (NaOH), as well as lye or potassium hydroxide (KOH).
Detailed explanation-3: -If the pH gets higher than 7.8, the water is becoming too alkaline. When water is too alkaline, it reduces the effectiveness of the chlorine-the pool chemical that kills pathogens. Water with a pH that’s too high also can cause skin rashes, cloudy water and scaling on pool equipment.
