Question

Which statement describes the change that occurs during the reaction of tin with lead(II) nitrate? A. Tin atoms give electrons to lead(II) ions and are reduced to tin(II) ions. B. Tin atoms accept electrons from lead(II) ions and are oxidized to tin(II) ions. C. Tin atoms accept electrons from lead(II) ions and are reduced to tin(II) ions. D. Tin atoms give electrons to lead(II) ions and are oxidized to tin(II) ions.

Answer 1

Answer is: D. Tin atoms give electrons to lead(II) ions and are oxidized to tin(II) ions.
Chemical reaction: Sn⁰ + Pb²⁺ → Sn²⁺ + Pb.
Tin atom (oxidation number 0) give two electrons to led ions, oxidation number of tin is greater now (oxidation number +2).
Oxidation is loss of electrons.
