Naming Salts (T4)

Question 1

Explain how the name of a salt is in two parts..

Answer 1

The first part of the name comes from the metal in the metal oxide, hydroxide or carbonate.

The second part of the name comes from the acid used to make it - eg, the names of salts made from hydrochloric acid end in CHLORIDE while the names of salts made from sulphuric acid end in SULPHATE.

Question 2

Sodium hydroxide reacts with hydrochloric acid to make..

Answer 2

Sodium chloride

sodium hydroxide + hydrochloric acid → sodium chloride + water

NaOH + HCl → NaCl + H2O

Question 3

Potassium hydroxide reacts with sulphuric acid to make..

Answer 3

Potassium sulphate

potassium hydroxide + sulphuric acid → potassium sulphate + water

2KOH + H2SO4 → K2SO4 + 2H2O

Question 4

Copper oxide reacts with hydrochloric acid to make..

Answer 4

Copper chloride

copper oxide + hydrochloric acid → copper chloride + water

CuO + 2HCl → CuCl2 + H2O

Question 5

Zinc oxide reacts with sulphuric acid to make..

Answer 5

Zinc sulphate

zinc oxide + sulphuric acid → zinc sulphate + water

ZnO + H2SO4 → ZnSO4 + H2O

Question 6

Calcium carbonate reacts with hydrochloric acid to make..

Answer 6

Calcium chloride

calcium carbonate + hydrochloric acid → calcium chloride + water + carbon dioxide

CaCO3 + 2HCl → CaCl2 + H2O + CO2

Question 7

Sodium carbonate reacts with sulphuric acid to make..

Answer 7

Sodium Sulphate

sodium carbonate + sulphuric acid → sodium sulphate + water + carbon dioxide

Na2CO3 + H2SO4 → Na2SO4 + H2O + CO2

Question 8

If mixing nitric acid with a base, what would be the second part of the resultant salt’s name?

Answer 8

Nitrate
