The hydronium lon concentration of a fruit juice is `4.6 xx 10^(-4) " mol " L^(-1)` . What is the pH of the juice?

Explanation

To find the pH of the fruit juice given the hydronium ion concentration, we can follow these steps:

### Step 1: Identify the formula for pH
The pH of a solution is calculated using the formula:
\[ \text{pH} = -\log[\text{H}_3\text{O}^+] \]
where \([\text{H}_3\text{O}^+]\) is the concentration of hydronium ions.

### Step 2: Substitute the given hydronium ion concentration
