Question 7

When is a salt produced?

Answer 7

When a metal ion replaces a H on an acid

Question 8

Salts of HCl are?
Salts of H2SO4 are?
Salts of HNO3 are?

Answer 8

Chlorides
Sulfates
Nitrates

Question 9

What happens in neutralisation reactions?

Answer 9

Bases and a carbonate react with acids, the base or carbonate accepts the H+ ions donated by the acid and the H+ ions of the acid are replaced by metal ions (or NH4+ ions) to form a salt
