EPA acidity test can be performed by titrating water sample to a pH of 8.2. What titrant in what concentration would you suggest for EPA acidity determination?

What do you think you would use to titrate an alkaline sample? How much alkalinity do you expect to find?

My school uses this lab as well; my guess would be to use a titrant that is alkaline instead of acidic. In the alkalinity determination, the sample is titrated with an acid, lowering the pH by a specified amount. To test acidity, and raise the pH, something like NaOH should do.

As for the concentration, I would say use a concentration similar to the concentration used in your lab; we used 2x10^-3 N.
