Background: A lab was performed where 5 different water samples were titrated with hcl from ph 6.5 - 4.2 in order to determine 1) buffer capacity in moles and 2) normalized alkalinity mg as CaCO3 / L

Questions:

1) using these values obtained, how do we determine the strongest/weakest buffer

2) what are some reasons that these values would fluctuate between other water samples
