Calculating pH of bases

Postby JohnWalkiewicz2J » Sun Dec 01, 2019 6:55 pm

How do you calculate the pH when a problem gives you the concentration of a base?

I think you can just find the pOH, which just uses the same equation as finding the pH, and then subtract that value from 14.

If you calculate the pOH with the OH- concentration, you can use the equation pH+pOH=14 to solve for pH. I hope this helps!

TO find ph, take the negative log of the base concentration (pOH) then subtract that amount from 14 to give you pH.
