The discussion focuses on calculating the change in pH when 10.0 mL of 1.0 M HClO4 is added to 990.0 mL of water, resulting in a pH change of 2. To determine this change, participants outlined the steps including writing the pH expression, assuming complete dissociation of HClO4, calculating the initial [H+] concentration, and determining the original pH. The new diluted concentration of HClO4 is then calculated to find the new [H+] and subsequently the new pH, allowing for the difference to be computed.
