Question: In the figure below, titration curves for strong acid
with strong base and weak acid with strong base are shown. Compare
the shapes of these curves early in the titration for three
different cases: titration of a strong acid, titration of a weak
acid with a lower pKa, and titration of a weak acid with a higher
pKa. Discuss with the class why the titration curve for weak acids
increase more rapidly early in the titration than do stronger...

An unknown acid is titrated with a strong base (NaOH) to produce
the above titration curve. Key points on this graph reveal
important information about the substance and the solution created
with it.
What volume of NaOH is needed to reach the equivalence point
(the point where you added equal moles of NaOH to the
acid)? Select one of the following : ["10 mL", "5
mL", "20 mL", "30 mL", "40 mL", "25 mL", "15 mL", "35 mL"]

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]

24A) 40mL of 0.2 M formic acid is titrated with a strong base
(NaOH= 0.5 M). Determine the pH before any base has been added.
Please show steps and please explain why the answer is what it
is.
24B) The 40mL 0.2 M formic acid is titrated with a 6.0mL of
strong base. Here NaOH can be treated as a conjugate base and
formic acid is the acid.
