2KMnO4 + 5H2SO3 ? K2SO4 + 2MnSO4 + 2H2SO4 + 3H2O
Calculate the mass of:
a. Sulphurous acid, H2SO3, required to react with 3.16 g of potassium permanganate, KMnO4
b. Manganese (II) sulphate produced when 5.65 g of potassium permanganate react with excess sulphurous acid
c. Potassium permanganate required to produce 5.00 g of manganese (II) sulphate.
