Reaction is: Pb(NO3)2(aq) + 2KI(aq) ---> PbI2(s) + 2KNO3(aq) 2.0 ml of 0.250M Pb(NO3)2 and 7.0 ml of 0.250M KI

A) In your experiment, one of the reagents was limiting and the other was in excess. Therefore after the lead(II)iodide precipitated from the solution, there were spectator ions left in the solution, and also the unreacted excess reagent. Assuming complete precipitation of lead (II) iodide, calculate the concentrations of each type of ion (Pb2+, K+, NO3-, I-) present in the solution after the PbI2 precipitated out.

Calculate the cell potential for the following reaction as written at 25.00 °C, given that [Cr2 ] = 0.834 M and [Sn2 ] = 0.0190 M. Standard reduction potentials can be found here.

Provide a high level (cartoon or box model) description of how an ICP-MS and how an IC work.

A solution contains 0.018 mol each of I– , Br– , and Cl– . Use the Ksp values given below to determine how much AgCl(s) precipitates out when this solution is mixed with 200 mL of 0.24 M AgNO3.

A student left 40.0 mL of a bottle of 12.0 M HCl out overnight. The next morning, the bottle has only 35.7 mL of liquid left. Assuming that the volume change is only due to loss of water, what will be the molarity if the remaining solution is diluted to 150 mL? a)3.20 M b)2.86 M c)6.0 M d)12.0 M
