I am having trouble with a question on bootcamp, I would appreciate any explanation! Here is the question:
What is the pH of a solution prepared by adding 20 mL of 0.02 M NaOH(aq) to 20 mL of water?
I get that we have to use M1V1=M2V2, but H2O has 2 H, while NaOH has 1 OH. I though that when this is the case, we have to use normality, so (1)(0.02)(0.02) = M2(0.04)(2).
Am I going about this the wrong way? Is it different because water is involved?
