Question

What happens when Cobalt (II) chloride is heated with water using a Bunsen burner.

A) Decomposition
B) Combustion
C) Oxidation
D) Reduction

Answer 1

When Cobalt (II) chloride is heated with water using a Bunsen burner, it undergoes a decomposition reaction, forming Cobalt hydroxide and Hydrochloric acid.

Step-by-step explanation:

When Cobalt (II) chloride is heated with water using a Bunsen burner, it undergoes a decomposition reaction. The formula for this reaction is:

CoCl₂(s) + 2H₂O(l) → Co(OH)₂(s) + 2HCl(g)

In this reaction, Cobalt (II) chloride breaks down into Cobalt hydroxide and Hydrochloric acid.
