Calculate the pH and pOH of each of the following solutions.

- Express your answer to two decimal places. Enter your answers numerically separated by a comma.

-A) [H3O+]= 1.6×10⁻⁸ M

-B) [H3O+]= 1.0×10⁻⁷ M

-C) [H3O+]= 2.5×10⁻⁶ M

Solutions

Expert Solution

A) [H3O+]= 1.6×10⁻⁸ M

PH = -log[H3O^+]

= -log1.6*10^-8

= 7.79

POH = 14-PH

=14-7.79 = 6.21

-B) [H3O+]= 1.0×10⁻⁷ M

PH = -log[H3O^+]

= -log10^-7

= 7.00

POH = 14-PH

= 14-7.00 = 7.00

-C) [H3O+]= 2.5×10⁻⁶ M

PH = -log[H3O^+]

= -log2.5*10^-6

=5.60

POH = 14-PH

= 14-5.60 = 8.40
