Answer 1

Solution part A)

Explanation:

To calculate the pH of a solution, use the equation

pH = −log[H3O+]

Since we are given the hydronium ion (H3O+) concentration of the solution, we can plug this value into the formula.

pH = −log[3.00×10−8M]
pH = 7.52

Solution part B)

Explanation:

To calculate the pH of a solution, use the equation

pH = −log[H3O+]

Since we are given the hydronium ion (H3O+) concentration of the solution, we can plug this value into the formula.

pH = −log[7.3×10−2 M]
pH = 1.14

Solution part C)

Explanation:

To calculate the pH of a solution, use the equation

pH = −log[H3O+]

Since we are given the hydronium ion (H3O+) concentration of the solution, we can plug this value into the formula.

pH = −log[4.00×10−11M]
pH = 10.40
