Answer

Answer:

A. $1.05\times 10^{-3}\text{ M}$

Explanation:

Step1: Identify the formula

We are given the formula $[\text{H}_3\text{O}^+]=10^{-\text{pH}}$.

Step2: Substitute the pH value

The pH of the lemon - juice is $\text{pH} = 2.32$. Substitute this value into the formula: $[\text{H}_3\text{O}^+]=10^{- 2.32}$.

Step3: Calculate the result

Using a calculator, $10^{-2.32}\approx1.05\times 10^{-3}\text{ M}$.
