    Subject: Chemistry SL Title: Preparation of a salt (lead iodide) by using precipitation method. Aim: To produce 1.50 g of lead iodide‚ PbI2‚ assuming 100 % conversion‚ using 1.00 g solid potassium iodide‚ KI‚ and 0.1 M lead nitrate‚ Pb(NO3)2 solution of volume 30 cm3 and hence calculate percentage yield. Calculations: 2KI(s) + Pb(NO3)2( aq) —> PbI2 (s) + 2KNO3 (aq) Mass of PbI2 to be produced = 1.5 g Moles of PbI2 = = 0.003 Moles of KI = 0.003*2 = 0.006 Mass of KI = 0.006*166 = 1.00 g
