Acids:
An acid is a substance that gives hydrogen ion H+or a hydronium ion H3O+when dissolved in water. A substance, which has an acidic nature, contains one or more hydrogen and an anionic group in its formula.
Example: H2SO4 (sulfuric acid) contains two hydrogens or hydrogen ion 2H+and sulfate anion
When sulfuric acid dissolves in water it produces Hydrogen ion or hydronium ion which is shown below
Base:
A Base is a substance which gives hydroxide ion OH-when dissolved in water.
Example
NaOH It is a base since it contains OH- ion or hydroxide ion.
