Chromium metal is immersed in an aqueous solution of cobalt(II) chloride. Express your answer as a chemical equation. Identify all of the phases in your answer. Enter noreaction if no reaction occurs.

The chemical equation is written below.

Explanation:

Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction.

The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series.

The chemical equation for the reaction of chromium metal and cobalt(II) chloride solution follows:

As, chromium lies above in the series. So, it can easily replace cobalt from its chemical reaction.

Hence, the chemical equation is written above.
