7 Solubility Product Determination: Pre-Lab Exercise Name Student ID Lab Section (L01, L02 or L50, L51) Bench Number These exercises are to be completed after you have read through the experiment and appropriate material in the textbook. They are to be turned in upon entering the laboratory. Write the balanced chemical equation for the reaction of oxalic acid and calcium hydroxide. Suppose you are determining K sp for the slightly soluble solid PbI 2 . Write the balanced chemical equation for solid PbI 2 as it dissolves. Write the K sp expression for solid PbI 2 as it dissolves. Fe 3+ reacts with dissolved I from a saturated PbI 2 solution according to 2Fe 3+ (aq) + 2I - (aq) 2Fe 2+ (aq) + I 2 (aq) The following data were obtained during the titration of a saturated PbI 2 solution with a Fe

Mass of FeCl 3 0.100 g Volume of FeCl 3 solution 100.0 mL Volume of FeCl 3 solution titrated 10.00 mL Volume of PbI 2 solution required to reach end point 24.35 mL Using this data, complete the problems on the next page. Solubility Product Determination 8 Calculate the molarity of the FeCl 3 solution. Calculate how many moles of Fe 3+ are contained in the 10.00 mL of FeCl 3 solution used in the titration. Calculate how many moles of I – from the saturated PbI 2 solution were reacted with the Fe 3+ . Calculate how many moles of Pb 2+ were present in the saturated solution. Calculate the molarity of the I – in the saturated solution. Calculate the molarity of Pb 2+ in the saturated solution. Calculate the K sp for PbI 2 solid....
