Question

Use the solubility generalizations on the information page to predict if one or more precipitates will form when aqueous solutions of zinc chloride (ZnCl2) and sodium carbonate (Na2CO3) are mixed. Write the formula of any precipitate that could form.

Answer 1

Answer: The formula for the precipitate formed is
`ZnCO_3`

Step-by-step 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 when aqueous solutions of zinc chloride and sodium carbonate are mixed:

`ZnCl_2(aq)+Na_2CO_3(aq)\rightarrow ZnCO_3(s)+2NaCl(aq)`
