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 ...

Aluminum (Al) has been considered as a material susceptible to corrosion, but it will become key to core technology in producing clean hydrogen energy. Recently, a POSTECH research team succeeded in ...

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.
