Titrations in Chemical Reactions problems

Acid-Base Titration example question

A 2.000-g sample of a sulfuric acid solution that is 96.5% H2SO4 by mass is dissolved in a quantity of water and titrated. What volume of 0.3580 M KOH(aq) is required for the titration? Assume that at the equivalence point the solution in the flask is K2SO4(aq).

Precipitation Titration example problem

A mixture of 0.1015 g of NaCl and 0.1324 g KCl is dissolved in water and titrated with 0.1500 M AgNO3(aq). What volume of the AgNO3(aq) will be needed to reach the endpoint?

Redox Titration example

A 20.00-mL sample of KMnO4(aq) is required to titrate 0.2378 g sodium oxalate in an acidic solution. How many milliliters of this same KMnO4(aq) are required to titrate a 25.00-mL sample of 0.1010 M FeSO4 in an acidic solution?

2MnO4(aq) + 16H+(aq) + 5C2O42−(aq) → 2Mn2+(aq) + 8H2O(l) + 10CO2(g)
