Q. 1 There are high levels of lead in drinking water of many cities which cause lead poisoning. The toxic level of lead is 5x10 ̶ 5 g/L. There are testing kits available for detecting lead. When these swabs are dipped in a solution that contain Pb2+ ions at a higher concentration than 5x10 ̶ 5 g/L it turns red. We have three solutions given below. Find out if these three solutions will test positive or not. (a) A solution obtained by dissolving Pb(IO3)2 in a solution of 0.10 M KIO3. (b) A solution prepared by dissolving PbI2 in a solution of 0.1 M Pb(NO3)2. (c) A solution that is obtained by mixing saturated solutions of PbI2 and Pb(IO3)2
