Answer to Question #156553 in General Chemistry for Julia

Question

50 ml of a .1 M sodium oxalate solution is titrated with .2 M potassium permanganate solution to its endpoint in acid solution. The redox products are manganese +2 ion and carbon dioxide gas. Determine the volume of potassium permanganate required to complete the titration.

Answer 1

M₁V₁ = M₂V₂

M₁ = 0.1M , V₁ = 50ml , M₂ = 0.2M , V₂ = ?

0.1M × 50 ml = 0.2M × V₂

V₂ = ( 0.1×50)/0.2

V₂ = 25ml

25 ml volume of potassium permanganate required to complete the titration
