consider the titration of a weak monoprotic acid (HA) with a strong base. If the titration has begun, but the equivalence point has not yet been reached, which of the following is true: A) The solution is a bugger and the HH equation can be used to compute the solution pH B) The excess titrant will dominate and control the pH at this point C) The dissociation of the weak acid to donate protons will determine pH - make a...

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
