Identify the reagents shown in bold in the following equations as nucleophiles or electrophiles :
`CH_3COOH + HO^(-) to CH_3 COO^(-) +H_2 O`

Explanation

To identify the reagents in the given equation as nucleophiles or electrophiles, we can follow these steps:

### Step 1: Understand the Reaction
The reaction provided is:
\[ \text{CH}_3\text{COOH} + \text{HO}^- \rightarrow \text{CH}_3\text{COO}^- + \text{H}_2\text{O} \]

### Step 2: Identify the Bold Reagent
The bold reagent in the equation is \(\text{HO}^-\) (hydroxide ion).
