calculate the solubility of Lead (IP) OXALATE, Pb((2O4)2 in a 0.018 M solution of potassium OXALATE K2 C2O4, in units of Molos/eiter. Kop For Pb (C2O4)2 = 6.17X10-26
What is the hydroxide-ion concentration of a 0.250 M sodium oxalate (Na2C2O4) solution?For oxalic acid (H2C2O4), Ka1 = 5.6×10–2 and Ka2 = 5.1×10–5.
04 (a) Calcium ions can be determined by precipitation of the oxalate according to the equation: Ca2+ (aq) + C2O42- (aq) = CaC204 (s) The solid may then be filtered off, washed and oxalic acid is regenerated by the addition of excess sulfuric acid. The amount of oxalic acid is then quantified by titration using potassium permanganate according to the equation: H2C204 + MnO4 + H+ = CO2 + Mn2+ + H20 (unbalanced) In an experiment to find the concentration...
