1. The problem statement, all variables and given/known data What is [H+] and pH for a 100 mM solution of KOH 3. The attempt at a solution This seems very simple..its only 2 marks but I dont know what I'm doing wrong. I understand KOH will dissociate into K+ and OH- pOH=-log(OH) ? ph + pOH = 14 p[OH]=-log[100x10^-6?] where and what am i doing wrong? Thanks for the help!!
