Question

What is the pH of a solution that has a H⁻ concentration equal to 1.7 x 10⁻⁵ M?

A. 0.22
B. 5.20
C. 10.20
D. 4.77
E. none of the above

Answer 1

The pH of a solution with a H⁻ concentration of 1.7 x 10⁻⁵ M is 4.77.

Step-by-step explanation:

The pH scale measures the concentration of hydrogen ions (H*) in a solution. A solution with a hydrogen ion concentration of 1.7 x 10⁻⁵ M would have a pH value of 4.77. According to the pH scale, a pH value of 7 is neutral, pH values less than 7 are acidic, and pH values greater than 7 are basic. Therefore, the correct answer is D. 4.77.

Answer 2

The pH of a solution with a H⁻ concentration of 1.7 x 10⁻⁵ M is 4.77.

Step-by-step explanation:

The pH scale measures the concentration of hydrogen ions (H*) in a solution. A solution with a hydrogen ion concentration of 1.7 x 10⁻⁵ M would have a pH value of 4.77. According to the pH scale, a pH value of 7 is neutral, pH values less than 7 are acidic, and pH values greater than 7 are basic. Therefore, the correct answer is D. 4.77.
