Question
The pH of a carbonated drink is 3.0. What is the hydrogen ion concentration of the drink?
A. 11 M
B. 3.0 M
C. 1 × 10⁻³ M
D. 1 × 10³ M
Solution
The pH of a solution is calculated using the formula pH = -log[H+], where [H+] is the concentration of hydrogen ions in the solution.
Given that the pH of the carbonated drink is 3.0, we can rearrange the formula to solve for [H+]:
[H+] = 10^-pH
Substituting the given pH value into the formula gives:
[H+] = 10^-3.0
Therefore, the hydrogen ion concentration of the drink is 1 × 10^-3 M. So, the correct answer is C.1 × 10^-3 M.
