mView?assignmentProblemlD-98144682 Aqueous Solutions Part A Imagine that you were to conduct an experiment by placing an aluminum wire into a solution of nickel chloride: 2 Al(s)+3NiC2(aq) What are the products of this reaction? >View Available Hint(s) O No reaction occurs, so there are no products. O 2 AKS)+3 NIS)+3 Cl2g) OACly(ag)+ Ni(S) 2Aici3(aq) + 3 Ni(s) Submit Part B We can also use the activity series to predict reactions between a metal and an acid. What are the products of the read View Available Hint(s) O Fe(s)+H2g) S02(9) + 02(g)Explanation / Answer
Option D is correct
This is an oxidation-reduction reaction:
Al = Al3+ + 3 e- : this is oxidation
Ni2+ + 2 e- = Ni : this is reduction
The number of electrons gained must equal the number lost, thus
2Al(s) = 2Al3+ + 6e-
3Ni2+ + 6e- = 3Ni(s)
Net equation: 2Al(s) + 3Ni2+ = 2Al3+ + 3Ni(s)
Molecular equation: 2Al(s) + 3NiCl2(aq) = 2AlCl3(aq) + 3Ni(s)
