Question

a use the rules for logarithms and exponents to solve for pH in terms of [H+]. NOTE: Capitalization counts. pH =?

Answer 1

To solve for pH in terms of [H+], use the formula pH = -log [H+]. Substitute the value of [H+] into the equation, calculate the logarithm, and take the negative to get the pH value.

Step-by-step explanation:

The pH of a solution can be calculated using the formula pH = -log [H3O+]. To solve for pH in terms of [H3O+], follow these steps:

1. Substitute the value of [H3O+] into the equation.
2. Use a scientific calculator to calculate the logarithm.
3. Take the negative of the logarithm to get the pH value.

For example, if [H3O+] is 1 × 10-3 M, the pH would be 3.0. If [H3O+] is 2.5 × 10-11 M, the pH would be 10.60.
