Question

Calculation of Hydrogen Ion Concentration from pH What is the H⁺ concentration of a solution with pH of

a. 3.82;
b. 6.52;
c. 11.11

Answer 1

The hydrogen ion concentration for a solution with pH of 6.52 is approximately 3.02 × 10-7 M, and for pH 11.11, it is approximately 7.76 × 10-12 M. A pH below 7 is acidic, while above 7 is basic.

Step-by-step explanation:

To calculate the hydrogen ion (H+) concentration from a given pH, we use the formula: [H+] = 10-pH. The pH of a solution is a measure of the acidity or basicity of the solution.

For a solution with a pH of 6.52:
The hydrogen ion concentration is [H+] = 10-6.52 M, which equals approximately 3.02 × 10-7 M.

For a solution with a pH of 11.11:
The hydrogen ion concentration is [H+] = 10-11.11 M, which equals approximately 7.76 × 10-12 M.

Given these concentrations, we can determine that a solution with a pH of 6.52 is weakly acidic, while a solution with a pH of 11.11 is basic. This is because a pH less than 7 indicates an acidic solution, while a pH greater than 7 indicates a basic (alkaline) solution.
