Question

When potassium chromate is added to solution if BaSO4 a precipitate is formed
Name the precipitate
Which type of chemical reaction is this

Answer 1

in this reaction barium chromate will be formed along with the Potassium Sulphate a yellow PPT will be observed in the reaction and this reaction is a type of double displacement reaction

Answer 2

Answer: The name of the precipitate is barium chromate. The type of chemical reaction is double displacement.

Explanation: -

$K_2CrO_4(aq)+BaSO_4(aq)\rightarrow K_2SO_4(aq)+BaCrO_4(s)$

Double displacement reaction is one in which exchange of ions take place.

In the given reaction barium chromate $(BaCrO_4(s))$ does not dissolve and hence remain as solid or a precipitate and potassium sulphate $K_2SO_4$ dissolves.
