Question

The pH of a carbonated drink is 3.0. What is the hydrogen ion concentration of the drink?

Answer 1

Answer:

$[H^+]=1\times10^{-3}M$

Explanations:

The formula for calculating the pH of the drink is expressed as:

$pH=-log[H^+]$

where:

[H+] is the hydrogen ion concentration

Given the following parameters

pH of the drink = 3.0

Substitute into the formula

$\begin{gathered} 3.0=-log[H^+] \\ -3.0=log[H^+] \\ [H^+]=10^{-3} \\ [H^+]=1\times10^{-3}M \end{gathered}$

Hence the hydrogen ion concentration of the drink is 1 * 10^-3M
