A chemist needs to determine the concentration of a sulfuric
acid solution by titration with a standard sodium hydroxide
solution. He has a 0.1799 M standard sodium hydroxide solution. He
takes a 25.00 mL sample of the original acid solution and dilutes
it to 250.0 mL. Then, he takes a 10.00 mL sample of the dilute acid
solution and titrates it with the standard solution. The endpoint
was reached after the addition of 14.33 mL of the standard
solution. What...

The concentration of Sn2+ in a solution is determined by
titration with a 0.1650 M permanganate solution. The balanced net
ionic equation for the reaction is:
2MnO4-(aq) + 5Sn2+(aq) + 16H3O+(aq) 2Mn2+(aq) + 5Sn4+(aq) +
24H2O(l)
(a) If 15.75 mL of the 0.1650 M permanganate solution are needed
to react completely with 30.00 mL of the Sn2+ solution, what is the
concentration of the Sn2+ solution? _________M

The concentration of a certain sodium hydroxide solution was
determined by using the solution to titrate a sample of potassium
hydrogen phthalate (abbreviated as KHP). KHP is an acid with one
acidic hydrogen and a molar mass of . In the titration, of the
sodium hydroxide solution was required to react with KHP. Calculate
the molarity of the sodium hydroxide.

The percentage of arsenic in a sample can be determined by
titration with iodine. In the determination, all of the arsenic
(As) in the sample is converted to HAsO2 followed by titration with
iodine (I2) solution. The chemical equation for the reaction
between HAsO2 and I2 is:
HAsO2 (aq) + I2 (aq) + 2 H2O (l) → H3AsO4 (aq) + 2 H+ (aq) + 2 I
