Question

what happens when aqueous solution of sodium sulphate and Barium Chloride are mixed give a balance equation for the reaction with state symbols name and define the type of chemical reaction involved in the above change

Answer 1

Na2SO4+BaCl2→2NaCl+BaSO4

As the reaction proceeds, the mixture will gradually turn cloudy. The reaction will produce Barium sulfate which is an insoluble white precipitate. Thus the mixture will be clear at the start of the reaction and gradually turn white and cloudy.

Answer 2

=> equation.
2NaSO4 ( aq.) + BaCl2( mix.) =====> BaSO4 + 2NaCl
now I balanced the equation
through the complete Valencey of the reactants and products.
I hope it's helpful to you
