Best ResponseYou've already chosen the best response.0100mM = 10*10^4 OR 1*10^3 [H+] = 1*10^3 pH = log 1*10^3 pH = 6.90

Best ResponseYou've already chosen the best response.0Oh, you're right. It should be 3. My mistake. I should of known it was wrong. a pH of almost 7 for HCl makes no sense :P

Best ResponseYou've already chosen the best response.0I don't get why it should be three  surely the pH is the log10 of the H+ concentration so it's log10(0.1) =1 so pH = 1. If it was 1M HCl the pH woould be 0, since log 10 of 1 is 0. pH=3 if the concentration of H+ is 1mM surely?
