Question

Aqueous solution of ZnSO₄ is added into the aqueous solution of BaCl₂, this is the exaple of ______ reaction.

Options

• displacement

• double displacement

• redox

• reduction

Answer 1

Aqueous solution of ZnSO₄ is added into the aqueous solution of BaCl₂, this is the exaple of double displacement reaction.

Explanation:

A double displacement reaction occurs when two ionic compounds in an aqueous solution exchange their ions to form two entirely new compounds. When this exchange produces an insoluble solid such as the barium sulfate formed in this example, the process is specifically referred to as a precipitation reaction.
