Recor all answers to the correct number of significant figures. d each answer in the space provided. Show all work for full credit, include units, and report 1. One of the reactions (Test Tube 1-5) has been designed such that neither lead nitrate nor potas- sium iodide are in excess. This tube is depicted in the far left of Figure 7.1. According to the figure, the secondary reactions with additional Pb(NO32 and KI should both be clear. Under the experimental conditions of the laboratory, it is unlikely that the supernatant from any test tube (1-5) was completely clear in the secondary reactions. Explain. what is the 1 In the nrevious experiment, Reactions and Stoichiometry I, FeCl

Explanation / Answer

Here, the reaction between lead nitrate and potassium iodide is Pb(NO3)2+2KI->2KNO3+PbI2.Here,products formed are precipitates.Thus,the supernatant is not a clear solution.
