← A 15.0 mL sample of sodium sulfite solution is acidified and needs 24.0 mL of 0.0120 mol/L permanganate. The ratio is 2 MnO₄⁻ : 5 SO₃²⁻. What is the concentration of the sulfite?Iron(II) oxalate, FeC₂O₄, is oxidised in acid, with Fe²⁺ → Fe³⁺ and C₂O₄²⁻ → 2CO₂. How many moles of electrons are lost when 0.30 mol of it reacts completely? →
