this acid base contains:
weak acids, and 3 equivalence points
then
ignore a; since H2CO3 only as 2 points
b) will be a good answer, but pH is low, therefore the titrant is NaOH, not H3PO4
c)
salt + HCl wont form this
d)
strong acid + storng base, do not expect this
e)
this is a good answer, since acid is being titrated by NaOH, there will be three eqoivalenc epoints!

Strong acid-titrated with strong base. Suppose the titration was reversed in question 2. If you titrated 30.0 mL of 0.1 M HCl with 0.1 M NaOH, indicate the approximate pH (a) at the start of the titration and (b) at the equivalence point. (c) What is the total volume of solution at the equivalence point? Add this curve to your sketch in question 2. 3. la. 1.0; b. 7.0; c. 60 mL]
Classify each titration curve as representing a strong acid titrated with a strong base, a strong base titrated with a strong acid, a weak acid titrated with a Strong base, a weak base titrated with a strong acid, or a polyprotic acid titrated with a strong base.
10.3 Titration curves are shown for two diprotic bases titrated with hydrochloric acid. Both bases are in the table of Ko values that is provided. Identify which base is titrated in each titration curve. Briefly explain how you know which base it is. (Hints: What is the relationship between Ko and PK, for a diprotic base? What is the relationship between pK, and pH in titration curves for weak acids and bases?) (a) Which weak base from the table is...
