$H C l + N a O H \to N a C l + {H}_{\text{2}} O$

#### Explanation:

Neutralisation is a chemical reaction where an acidic and a basic solution react, resulting in a "reset" of their pH - thus forming a salt, and water.

There are two types of acids and bases: strong and weak. A strong acid must react with a strong base in order to neutralise. Likewise a weak acid must react with a weak base.

E.g.

$H C l + N a O H \to N a C l + {H}_{\text{2}} O$

Here, $H C l$ is a strong acid and $N a O H$ is a strong base.

Most acids are weak, while most bases are strong. I will not go in depth of each because it is irrelevant to neutralisation, but essentially, it is the same process.

Hope this helps :)
