2. Monoprotic acid , as it contains only one equivalence point. As i have given example in a photo for the graph for triprotic acid that you can compare.
3.Unknown acid is a weak acid since point of equivalence is
above 7 ph , if it were a strong one the point would be near to 7
ph.

Question 3: Draw the titration curve (pH versus mL of NaOH added) that would be obtained from the titration of 30 mL of a 0.10 M solution of an unknown triprotic acid, H3A (Kat = 1.26 x 10-3; Ka2 = 5.6 x 10-6, Ka3 = 3.32 x 10-10) with 0.10 M NaOH. Indicate the volume needed to reach the first second, and third equivalence points and the pH at the half equivalence points for the three titration regions.

The chart below has entries for several steps along the titration curve (which shows the pH as a function of the volume of NaOH solution added). To calculate the pH at each step, you must first understand what species are present and which chemical reactions are occurring, as that will dictate the method needed to calculate the pH. For each volume listed, Fill in the table with the major species (one or more) present in solution that could impact the...
