Understanding pH and Hydrogen Ion Concentration
* pH: A measure of the acidity or alkalinity of a solution. Lower pH values indicate higher acidity, while higher pH values indicate higher alkalinity.
* Hydrogen Ion Concentration ([H+]): The concentration of hydrogen ions (H+) in a solution.
The Relationship
The pH and hydrogen ion concentration are related by the following equation:
pH = -log[H+]
Solving the Problem
1. Find the [H+] of Solution A:
* Using the equation above, rearrange to solve for [H+]:
[H+] = 10^(-pH)
[H+] of Solution A = 10^(-5) M
2. Calculate the [H+] of Solution B:
* Solution B has 100 times the [H+] of Solution A:
[H+] of Solution B = 100 * 10^(-5) M = 10^(-3) M
3. Find the pH of Solution B:
* Using the pH equation:
pH of Solution B = -log(10^(-3)) = 3
Therefore, the pH of Solution B is 3.
