Neutralisation is the reaction of an acid with a base that results in the pH moving towards 7. It is a useful process that occurs in everyday life such as in the treatment of acid indigestion and ...

The alkaline diet is reshaping how people view nutrition by focusing on pH balance to promote better health and long-term ...

All alkaline solutions contain more hydroxide ions than hydrogen ions. Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base ...
