Question

The reaction in which the ions in the reactants are exchanged to form a precipitate
are called double displacement reactions.
Recall the activity (3) in which you added potassium chromate (K, Cro) into the
solution of barium sulphate (BaSO.).
1. What was the colour of the precipitate formed ?
2. Write the name of the precipitate.
3. Write down the balanced equation for this reaction.
4. Will you call this reaction a displacement reaction or a double displacement reaction.​

Answer 1

Answer:

1 white

2 barium sulphate

4 we will call as double displacement reaction
