Question

3 mL of sodium sulphate solution and 3 mL of barium chloride solution is mixed in a test tube. The chemical formula and colour of the solid product formed isBaSO3 and red
(a) BaSO3 and red


(b) BaSO4 and green


(c) NaCl and white


(d) BaSO4 and white

Answer 1

Answer:

option d is the right answer

Na2So4+Bacl2----Baso4+2Nacl

in which colour of solid precipitate baso4 is white

Answer 2

Answer:

Option D

Explanation:

The reaction between sodium sulphate and barium chloride is basically a  double displacement reaction. The chemical equation of the said reaction can be written as

Na2​SO4​+BaCl2​⟶2NaCl+BaSO4​

Now in the reaction, the products formed are Barium sulphate and sodium cholride, which is a salt and gets dissolved in the solution. Barium sulphate is not soluble and it forms a white precipitate

Hence Option D is correct
