Question 1
A monoprotic solid acid, Potassium Hydrogen Phthalate (aka,
KHP), KHC8H4O4,
(molar mass = 204.22 g/mol) is used to standardize solutions of
NaOH. (see KOTZ p. 218, and problem 72.)
A student weighs out 1.3009 g of KHP and
dissolves it in some water. The student then performs a titration
with a solution of unknown concentration of NaOH, using 41.20 mL to
reach the equivalence point.
What is the Molarity of the NaOH solution?

A sample of potassium hydrogen phthalate (KHC8H4O4), which is an
acid, with a mass of 0.7292 g is dissolved in water and used to
standardize a solution of cesium hydroxide. An endpoint is reached
when 34.61 mL of cesium hydroxide has been added. Determine the
molarity (in mol/L) of the cesium hydroxide solution. Report your
answer to four significant figures.

(13) Hydrogen phthalate ion,
HC8H4O4–, from
potassium hydrogen phthalate (abbreviated as “KHP”; formula =
KHC8H4O4), is a weak acid. In an
acid-base titration, a 50.0-mL solution of 0.100 M “KHP”
solution is titrated with NaOH solution of unknown concentration.
The following net ionic equation represents the reaction that
occurs during titration:
HC8H4O4–(aq) +
OH– (aq) →
C8H4O42–(aq) +
H2O(l)
(a) If the titration requires 34.0 mL of NaOH
solution to reach equivalent point, calculate the molar
concentration of NaOH...
