For the 0.01 M NaOH and 0.001 M NaOH solutions in Part A, do your calculated values of [OH-] agree with those you would predict using the dilution equation. M1V1=M2V2, where M1= the calculated [OH-] of the 0.1 M NaOH stock solution.
We measured pH and calculated H+ and OH- concentration. Would the dilution equation work
