HCl+Hg

The reaction between hydrochloric acid (HCl) and mercury (Hg) primarily leads to the formation of mercurous chloride (Hg₂Cl₂), commonly known as calomel. The reaction can be represented as follows:

\[ \text{Hg} + 2 \text{HCl} \rightarrow \text{Hg}_2\text{Cl}_2 + \text{H}_2 \]

This reaction is notable as calomel has various applications, especially in electrochemistry and as a component of some medicinal preparations. However, it is important to note that mercury is a toxic substance and should be handled with care, adhering to safety protocols.
