An acid and a base neutralise each other to form:
salt along with hydrogen gas.
salt along with oxygen gas.
The correct option is B salt along with water.
When definite amounts of acid and base are mixed, they neutralise each other to form salt and water. For example: Hydrochloric acid reacts with sodium hydroxide to form sodium chloride and water. This can be represented as:
Hydrochloric acid + Sodium hydroxide → Sodium chloride + Water
