CHEMISTRY HELP PLEASE! Im calculating pH balances for solutions.
I need 2 calculations for one acid and one base!

The acid: 0.001 M HCl

The base: 0.001 M NaOH.

I already know that 0.001 M HCl = a pH of 3. (acid)

And 0.001 M NaOH = a pH of 9. (base)
But I still need help proving this with calculations. Thanks! :)
