According to the balanced chemical equation 5 H₂C₂O₄(aq) + 2 MnO₄^-(aq) + 6 H⁺(aq) → 10 CO₂(g) + 2 Mn²⁺(aq) + 8 H₂O(l)
0.3500 grams of oxalic acid,H₂C₂O₄ will react with ________ mL of 0.100 M potassium permanganate,KMnO₄ solution.

Question

Quizplus · Accepted Answer

To balance the equation, we need 5 moles of oxalic acid for every 2 moles of potassium permanganate. Therefore, 0.3500 g of oxalic acid will react with:(0.3500 g oxalic acid) x (1 mol oxalic acid/90.03 g oxalic acid) x (2 mol potassium permanganate/5 mol oxalic acid) x (1000 mL potassium permanganate/1 mol potassium permanganate) x (1 L/1000 mL) = 15.5 mL potassium permanganate

According to the Balanced Chemical Equation 5 H2C2O4(aq)+ 2 MnO4-(aq)

According to the Balanced Chemical Equation 5 H₂C₂O₄(aq)+ 2 MnO₄^-(aq)
