Methylamine in water reacts with ferric chloride to precipitate ferric hydroxide. Explain.

Explanation

To explain why methylamine in water reacts with ferric chloride to precipitate ferric hydroxide, we can break down the process into several steps:

### Step 1: Understanding Methylamine in Water
Methylamine (CH₃NH₂) is a weak base. When it is dissolved in water, it can accept a proton (H⁺) from water, leading to the formation of methylammonium ions (CH₃NH₃⁺) and hydroxide ions (OH⁻).

**Reaction:**
\[ \text{CH}_3\text{NH}_2 + \text{H}_2\text{O} \rightleftharpoons \text{CH}_3\text{NH}_3^+ + \text{OH}^- \]
