What would happen if OH-ions were added to a very basic solution?

Answer:

It would make the solution more basic, but probably not much so.

Explanation:

Say you have a solution of pH=12, that means there are #10^-2# moles of #OH^-# already present. To raise this to pH=13, you'd have to add #9.9xx10^-2# moles of #OH^-#, almost 10 times as much as already present.
Doubling the number of #OH^-#-ions would only raise the pH by 0.3 points.
