Neutralization – Application Reaction and Solved Examples
Neutralization – Application Reaction and Solved Examples

‘Neutralisation’ or ,Neutralization, definition is a chemical reaction in which an ,acid, reacts with a base or alkali to form water and salt. In the reaction, the H + ions of Hydrogen in an ,acid, combine with the OH-(hydroxide) ions of the basic solution, and this is how water is formed from ,neutralization,. The neutralized solution usually has a ph seven value, but the pH value can differ ...
