Question

Q10 a) What happen when a piece of iron metal is placed in copper sulphate solution ? Name the type of reaction.
b) Write the balanced chemical equation for the following " Barium chloride solution reacts with sodium sulphate solution to give insoluble barium sulphate and a solution of sodium chloride

Answer 1

✓It is displacement reaction
✓ BaCl2 +Na2So4 =BaSo4 2NaCl

Answer 2

ANSWER

a)

When a piece of iron metal is placed in copper sulphate , then ferrous sulphate solution and copper metal are formed.

This is a type of displacement reaction.

b) The chemical reaction equation for the reaction will be as follows.
