WebThe pH of a solution is determined by taking the negative log of the concentration of hydrogen ions in solution. HCl is strong acid so it completely dissociates in solution. So adding .0001 M HCl is the same as saying that 1 *10-4 moles of H+ ions have been added to solution. The -log[.0001] =4, so the pH of the solution =4. WebAnswer: You need to bear in mind: 1. pH = -log[H+] 2. HCl is a strong acid, completely dissociated in water. Therefore, a concentration of HCl = 2*10^-8 M 3. H2O dissociates (H2O = H+ + OH-, Ka = ~10^-14) and therefore, water contributes 10^-7 M H+. Normally, this is small compared to the concen...
