Which expression defines pOH

Log 1/[OH-]

Determine the pH and pOH of a solution that is 0.010 M HCl

PH = 2.00 + pOH = 12.00

For a given solution, which equation relates the values of pH and pOH

pH + pOH = 14.00

The pKa of acetic acid is 4.76. If the concentration of acetate ion is equal to 0.0010 M and the concentration of acetic acid is 1.00 x 10^-3 m. What will be the pH

pH = 4.76

Calculate the pH and pOH of a solution that has concentration of 0.00010 m NaOH
