A soluble base dissolves in water to form an alkaline solution. During neutralisation the H + ion from the acid joins with the OH-ion from the alkali. This is why water is formed in these reactions.

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 ...

A hydrogen atom from the carbonic acid bonds to the carbonate ion in ocean water and creates a bicarbonate ion (HCO-3) which the shell-making organisms can’t use.

Cyanide salts and solutions are extremely poisonous. Reaction with acid liberates hydrogen cyanide gas, one of the most toxic and rapidly acting poisons. Solutions must be kept basic (pH>8). Gloves ...
