Worksheet: Titration Calculations
In this worksheet, we will practice using titer volumes measured in a titration to calculate the analyte concentration or solute composition.
Oxalic acid is a diprotic acid. A solid sample with a mass of 0.7984 g, containing oxalic acid, was titrated against 0.2283 M aqueous sodium hydroxide. Calculate the percent mass of oxalic acid in the sample given that 37.98 mL of the sodium hydroxide solution was needed to reach the endpoint of the titration.
Sulfuric acid is a diprotic acid. A 31.5 mL aliquot of aqueous sulfuric acid was titrated against 0.0134 M aqueous sodium hydroxide. Calculate the molar concentration of the aqueous sulfuric acid given that 23.9 mL of the sodium hydroxide solution was needed to reach the endpoint of the titration.
A solution of is titrated against a standard 0.0100 M solution of . When cyanide ions are in excess, the silver ions react to produce the soluble complex. However, when silver ions are in excess, solid precipitates. If begins to precipitate after the addition of 28.72 mL of the titrant, how many grams of are present in the analyte solution?
