Answer 1

Answer:

1st answer.

Yellow

The color of barium chromate precipitate is Yellow.

The reactants involved in this reaction are potassium chromate and barium sulfate. The potassium chromate is yellow and is in powdered form. Barium sulfate is white and when it is mixed in water, it gives a solution which is milky white.

2nd answer.

Now, when we will add the milky-white solution to the potassium chromate, a new product is formed known as barium chromate which is yellow in colour. In this reaction, K2CrO4 is potassium chromate, BaSO4 is barium sulphate, K2SO4 is potassium sulphate, and BaCrO4 is barium chromate.

3rd answer.

Barium sulphate and potassium chromate chemical equation

Now, when we will add the milky-white solution to the potassium chromate, a new product is formed known as barium chromate which is yellow in colour. In this reaction, K2CrO4 is potassium chromate, BaSO4 is barium sulphate, K2SO4 is potassium sulphate, and BaCrO4 is barium chromate.

4th answer.

In this reaction, K2CrO4 is potassium chromate, BaSO4 is barium sulphate, K2SO4 is potassium sulphate, and BaCrO4 is barium chromate. This reaction takes place by double-displacement. Thus, the barium chromate formed is yellow in colour. The correct option is C.
