Chapter 17, Problem 2ST

Interpretation Introduction

Interpretation:

The substance that is oxidized in the redox reaction $\text{Zn}\left(s\right)+{\text{Cu}}^{2+}\left(aq\right)\to {\text{Zn}}^{2+}\left(aq\right)+\text{Cu}\left(s\right)$, is to be predicted.

Concept introduction:

A species gains or loses electrons to form anions or cations respectively. A gain in electron is classified as a reduction reaction and loss of electron is classified as an oxidation reaction. To keep a track on the loss or gain of an electron, a number is assigned in the form of oxidation number.
