Question

aqueous solution of sodium chloride sodium sulphate and calcium chloride and are taken in three separate test tube using aqueous Brahmam chloride how do you identify sodium sulphate​

Answer 1

Answer:

Exchange of ions between both the reactants takes place; therefore, it is an example of "Double Displacement Reaction". Since, precipitate of barium sulphate forms, it is also a "Precipitation Reaction".

Explanation:

The balanced chemical reaction is given as follows:

Na2SO4(aq)+BaCl2(aq)→BaSO4(s)+2NaCl(aq

AgNO3 (aq)+NaCl(aq)→AgCl(s)+NaNO 3(aq)
