Write balanced chemical equations for the preparation of the following salts in the laboratory:
A soluble chloride by the action of an acid on a metal.

Explanation

To prepare a soluble chloride salt by the action of an acid on a metal, we can follow these steps:

### Step 1: Identify the Metal and Acid
We will use sodium (Na) as the metal and hydrochloric acid (HCl) as the acid.

### Step 2: Write the Reaction
When sodium reacts with hydrochloric acid, it produces sodium chloride (NaCl) and hydrogen gas (H₂).
