Answer to Question #313378 in General Chemistry for Moya

Question

2AgNO3+Ni→Ni(NO3)2+2Ag

Answer 1

Ni (s) + 2 AgNO₃ (aq) → Ni(NO₃)₂ (aq) + 2 Ag (s)

This is an oxidation-reduction (redox) reaction:

2 Ag^I + 2 e^- → 2 Ag⁰

(reduction)

Ni⁰ - 2 e^- → Ni^II

(oxidation)

AgNO₃ is an oxidizing agent, Ni is a reducing agent
