A Solution Was Made by Taking 2

Short Answer

A solution was made by taking 2.500 g of KMnO₄ and dissolving it in enough water to make 1.000 liter of solution. This solution was used to titrate H₂C₂O₄·2H₂O, which can be readily obtained in high purity. In acidic media, the reaction is:2 MnO₄^-(aq)+ 5 H₂C₂O₄(aq)+ 6 H⁺ → 10 CO₂(g)+ 2 Mn²⁺(aq)+ 8 H₂O How many mL of this solution are required to titrate a 0.480 g sample of H₂C₂O₄·2H₂O? Hint: Remember to use moles as an intermediary when performing your stoichiometry calculations for the titration.
