What is the molarity of Cl- in each solution?
a. 0.200 M NaCl
b. 0.150 M SrCl2
c. 0.100 M AlCl3
Solution 56E: Solution: Here, we are going to write the balanced chemical equations for the given set of reactions with the help of reactivity series. Step1: The reactivity series is a list of metals arranged in the order of their decreasing activities. We can say that all metals are not equally reactive. That is why, reactive metals can displace less reactive metals from their compounds in solution or molten form. In order to know, which metal is more reactive, several experiments were performed, and finally a series known as the reactivity or activity series was developed. Step2: a) Nickel metal is added to a solution of copper(ll) nitrate Since Nickel is placed above copper in the reactivity series, it is more reactive than copper. Hence, it will displace copper from its nitrate solution. The balanced chemical equation is: Ni(s) + Cu(NO ) 3 2-------> Ni(NO ) (aq3 2u(s) b) A solution of zinc nitrate is added to a solution of magnesium sulfate Since, none of the reactant metals are in elemental form so no reaction takes place between...
