Bases, they can neutralise acids.

Question 2

Why is water formed in neutralisation reactions?

Answer 2

The H+ ion from the acid joins with the OH- ion from the alkali, making water.

Answer 4

1. Acid + Metal → Salt + Hydrogen
2. Acid + Metal Hydroxide → Salt + Water
3. Acid + Metal Oxide → Salt + Water
