Question

Can a solution of Sn(NO3)2 be stored in an aluminum container?

Answer 1

You're predicting whether \(Sn^{2+}\) would oxidize \(Al_{(s)}\)(a redox reaction). Use their the reduction potentials (from a table) and determine whether the reaction: \(Sn^{2+}+Al_{(s)}\rightarrow Sn_{(s)}+Al^{3+}\) is spontaneous, i.e. \(E_{cell}=+ve\).
