Further Neutralisation Reactions

Question 1

Metal salt

Answer 1

When the hydrogen part of the acid is replaced by the metal part of the alkali

Question 2

Neutralisation

Answer 2

A reaction that occurs when the acid is cancelled down by the alkali

Question 3

What happens when you add a metal carbonate to acid?

Answer 3

Heat is evolved, metal carbonate disappears and effervescence or fizzing is observed.

Question 4

General equation for acids reacting with carbonates

Answer 4

Acid + Carbonate –> Salt + Water + Carbon Dioxide
