Q1. The concentration of Pb+ in sample of wastewater is to be determined by using gravimetric analysis? to a 1000.0 ml sample of the waste water is added an excess of sodium sulfide, forming insoluble lead II sulfide(239.266g/mol) according to the balance equation given below. the solid leadII sulfide is dried, and it’s mass is measured to be 0.1209g. what was the contraction of Pb2+ in the original wastewater sample?Pb2+(aq) + Na2S(aq) —> PbS(s) + 2Na+(aq)
