Identify the acid which matches the following description
The acid on mixing with silver nitrate solution produces a white precipitate which is soluble in excess ammonium hydroxide.

Explanation

To identify the acid that matches the given description, we can follow these steps:

### Step 1: Understand the Reaction
The problem states that an acid reacts with silver nitrate (AgNO3) to produce a white precipitate. This indicates that the acid must contain a negatively charged ion (anion) that can react with silver ions (Ag+) to form a precipitate.

### Step 2: Identify the Precipitate
The white precipitate formed when silver nitrate reacts with certain acids is typically silver chloride (AgCl). This suggests that the anion from the acid is chloride (Cl-).
