SrCl2 (aq) + K2CO3 (aq) —&gt;
Wewaii [24]

Answer: SrCl_2(aq)+K_2CO_3(aq)\rightarrow 2KCl(aq)+SrCO_3(s)

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.

The balanced chemical equation is:

SrCl_2(aq)+K_2CO_3(aq)\rightarrow 2KCl(aq)+SrCO_3(s)
