(This question ties to question 18) The balanced reaction between oxalate and permanganate ion is shown below. 5C2O42- + 2MnO4 + 16H+ → 10CO2 + 8H2O + 2Mn2+ During the standardization of KMnO4, a 28.0 mL of KMnO4 has been used to neutralize 0.200 g of Na2C2O4 (MW = 134 g/mol). Based on the balanced reaction, determine the moles of permanganate KMnO4 in 28 mL Hint: Identify the mole ratio between oxalate and permanganate

A 200.00 g of city water was evaporated to complete dryness. Data obtained during this experiment: Weight of the empty beaker: 157.72 g Weight of the beaker with residue (impurities): 160.06 g Calculate the impurities in the city water in PPM Hint: ppm = (weight of the residue in g / weight of the sample ) x 106
