1. If a strong acid and weak acid have the same concentration of acid, explain why they will have a different pH.
2. Explain why it is important to prime the pipette.
3. When using the titration technique explain why the beakers that contain the acid solutions must be dry before the acid is added, but the volumetric flask and Erlenmeyer flasks may have some deionized water drops in them before they are used.© BrainMass Inc. brainmass.com July 21, 2018, 2:10 am ad1c9bdddf

1. If a strong acid and weak acid have the same concentration of acid, explain why they will have a different pH
pH is measured based on the concentration of H3O+ present in the solution. And the concentration of H3O+ depends on the extent of dissociation of the acid. That is, if you have a 1.0 M HCl, the concentration of H3O+ present in the solution will be 1.0 M because HCl is a strong acid and it dissociates 100 %.
HCl + H2O < H3O+ + Cl-
Whereas for 1.0 M of weak acid, for example HA, it will NOT dissociate 100 %.
HA + H2O H3O+ + A-
The concentration of H3O+ will not be 1.0 M.
2. Explain why ...
This solution provides answer to a number of questions about titration techniques.
