The problem asks us to calculate the ion concentration of a saltwater solution given that it has a pH of 8. We assume it is asking for the hydrogen ion concentration, $[H^+]$.

1. Problem Description

The problem asks us to calculate the ion concentration of a saltwater solution given that it has a pH of

8. We assume it is asking for the hydrogen ion concentration, $[H^+]$.

2. Solution Steps

The pH is related to the hydrogen ion concentration by the following formula:

$pH = -log_{10}[H^+]$

We are given that $pH = 8$.

We can rearrange the formula to solve for $[H^+]$:

$[H^+] = 10^{-pH}$

Substituting the given pH value into the formula, we get:

$[H^+] = 10^{-8}$

3. Final Answer

The ion concentration is $10^{-8}$.
