a. What is the pH of a 6.1 ✕ 10-5 M Ca(OH)2 solution?


b. What is the H3O+ concentration of the solution?

I just cant figure out the ionic equation.

Perhaps this will help.
Ca(OH)2 ==> Ca^2+ + 2OH^-
Thanks! I got part A but how are you supposed to know the concentration of H30+ if its not in the equation?
See your follow up post above.
