Which solution will form a precipitate when mixed with a solution of aqueous na2co3? which solution will form a precipitate when
trapecia [35]

Answer:

CuCl_{2}(aq.) will form a precipitate of insoluble CuCO_{3} when aqueous Na_{2}CO_{3} is added.

Explanation:

According to solubility rule-

all carbonates are insoluble except group IA compounds and NH_{4}^{+}

all salts of sodium are soluble

When Na_{2}CO_{3} is added to given solutions, a double displacement reaction takes place in each solution to form a sodium salt and a carbonate salt.

So, in accordance with solubility rule, addition of Na_{2}CO_{3} into CuCl_{2}(aq.) will result precipitation of insoluble CuCO_{3}

Reaction: Na_{2}CO_{3}(aq.)+CuCl_{2}(aq.)\rightarrow 2NaCl(aq.)+CuCO_{3}(aq.)
