Calculate the molecular weight of the unknown metal cation. Hint: Is the precipitate in the second reaction a pure metal? g/mol What is the identity of the metal in the unknown solution?
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
