Answer:
![[H^+]=1*10^(-3)M](https://img.qammunity.org/qa-images/2023/formulas/chemistry/college/idmwd5zqm8fear3bpvwr.png)
Explanations:
The formula for calculating the pH of the drink is expressed as:
![pH=-log[H^+]](https://img.qammunity.org/qa-images/2023/formulas/chemistry/college/7tcznskgifavo8jpuq5r.png)
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*10^(-3)M \end{gathered}](https://img.qammunity.org/qa-images/2023/formulas/chemistry/college/3wai68mdjejbsvqb2nuv.png)
Hence the hydrogen ion concentration of the drink is 1 * 10^-3M
