|The pOH Scale|
|The pOH scale is the corollary of the pH scale.
|ie. pH + pOH = 14 You'll remember from math class that when
you multiply two numbers you only add their logs.
|[H3O+] = (1.0 x 10-7 )*(1.0
x 10-7) = 1.0 x 10-14
-log[H3O+] = 7 + 7 = 14
|Thus a solution that has a pH = 7 must also have a pOH = 7.
|What is the pOH of a 0.010 mol/L NaOH solution?
|What is it's pH?
|What are the hydronium ion and hydroxide ion concentration of
a solution prepared by adding 1 mL of 1.0 mol/L HCl to 9 mL of water? Assume
that volumes are additive and that the 1 mol/L HCl dissociates completely.
|What are the hydronium ion and hydroxide ion concentrations
of a solution made by adding 1 mL of 0.1 mol/L NaOH to 9 mL of water?
|Find the pH, pOH, [OH-] of a 0.00010 mol/L HCl solution.
|Find the pH of a 0.00325 mol/L NaOH solution.
|What is the hydronium ion concentration of a solution that has a pH = 2.6?|
