Question

Instead of following the procedure for laboratory assignment 3 exactly, a student placed the Pb(NO3)2 solution in the test tube and then added NaI solution. What, if any, effect would the procedural change make on the student's results for this test?

Explanation / Answer

There is no effect of notfollowing the procedure for laboratory assignment 3 exactly, a student placed the Pb(NO3)2 solution in the test tube and then added NaI solution.

because the reaction b/w Pb(NO3)2 and NaI does not change by changing the order of addition.

the reaction is

Pb(NO3)2 (aq) + 2 NaI (aq) ----------> PbI2 (s) + 2 NaNO3 (aq)
