Question

If the solution of K2CrO4 (potassium chromate) is mixed with barium

sulphate solution (BaSO4) __________

(a) What is the colour of the precipitate formed?

(b) Name the precipitate.

(c) What is the type of chemical reaction? Define it.

(d) Write the balanced chemical equation.​

Answer 1

(a) What is the colour of the precipitate formed?

☞The colour of ppt is yellow.

(b) Name the precipitate.

☞Barium chromate (BaCrO4)

(c) What is the type of chemical reaction? Define it.

☞ This is a double displacement reaction.

Double displacement reaction:- The reaction in which exchange of ions takes place to form precipitate is called as Double displacement reaction

(d) Write the balanced chemical equation.

k2CrO4+BaSO4➜K2SO4+ BaCrO4

potassium + Barium ➜ Potassium Barium

chromate Sulphate Sulphate chromate
