how to calculate PH and POH

{OH-) = 1.0 *10 to -11 power M?

pOH = -log(OH^-)

pH + pOH ==> pKw = 14

Calculate the mass of strontium hydroxide required to make a 450-mL solution with a pOH of 4.00.Step 1: Find pOH. I found that

Top answer: The pOH is 10. To convert pOH = 10 to OH^-, it is pOH = -log(OH^-) 10 = -log(OH^-) -10 = log(OH^-) Read more.
Sometimes the basicity of a solution is reported using pOH (pOH = -log[OH-]). What is thea. [OH-] if pOH = 1.90 b. [H3O+] if pOH
