Best ResponseYou've already chosen the best response.1If HCl is a strong acid  meaning it dissociates 100%  then use \(\sf pH=log[H_3O^+]\)

Best ResponseYou've already chosen the best response.1The pH is equivalent to the log of the H+ concentration. pH = log[H+] The P infront of the H means take the log of something. log[2x10^10] Remember pH is a relative term, just says the concentration of H+ ions in a solution, but doesn't give you the sense how strong an acid is, for that we use Ka values.

Best ResponseYou've already chosen the best response.0I put it in the calculator and got 9.6989 so I'm assuming that's the answer, thanks guys :)

Best ResponseYou've already chosen the best response.1Yes 9.69 is the answer! And remember the product of [H+][OH] = 10^14
