Question
An unknown solution labeled only by its concentration was analyzed. It was labeled to have "1.000 M X(NO3)," and known to be a metal cation. To find out to identity of the cation, a 10.00 mL aliquot of the solution was reacted with 10.00 mL of 1.000 M NAOH solution and heated according to the reactions below: (1st reaction) X(NO3)2 + 2 NaOH → A + 2 NaNO3 (2nd reaction) A + heat → B + H20

What is the identity of A and B in terms of X? Include states identity of A: Pb(OH) state: solid identity of B: Pbo state: solid Calculate the theoretical moles of NaOH needed to FULLY consume all the X(NO3)2 in the solution. mol NaOH What is the limiting reactant for the first reaction? Calculate the theoretical amount of the metal precipitate (B) formed in the second reaction. moles From the solution in Products 2, it was filtered and heated further until it was dried. This produced a precipitate with 0.3592 g. Calculate the molecular weight of the unknown metal cation. g/mol Hint: Is the precipitate in the second reaction a pure metal? What is the identity of the metal in the unknown solution?
