First you recognize that HCl is a strong acid and ionizes completely; therefore,
HCl + H2O ==> H3O^+ + Cl^-
So if you start with 0.00010 M HCl,knowing it is ionized completely, the H3O^+ must be 0.00010.
pH = -log(H^+) = -log(0.00010) = -(-4.0) = 4.0 and pH = 4.0
Calculate the hydrogen ion concentration and the pH of each of the following solutions of strong acids.
(a) 0.00010 M HCl
if you could just explain how to do this that would be great!
thanks
