Chapter 7: Problem 14

Fill in the blanks. In cell representation, oxidation half-cell is represented on the ___ .

Short Answer

Expert verified
Question: In a cell representation, the oxidation half-cell is positioned on the ______ side. Answer: left

Step by step solution

01

Understanding cell representation

A cell representation is a symbolic representation of a galvanic (voltaic) cell, which is a device that generates electrical energy through redox reactions. In a cell representation, each half-cell (electrode) is represented by its corresponding chemical species with a double vertical line (||) representing the salt bridge and a single vertical line (|) separating the chemical species in each half-cell.
02

Oxidation and Reduction Half-Cells

In a galvanic cell, there are two half-cells – the oxidation half-cell and the reduction half-cell. In the oxidation half-cell, oxidation (loss of electrons) occurs, whereas in the reduction half-cell, reduction (gain of electrons) takes place.
03

Position of Oxidation Half-Cell in Cell Representation

In a cell representation, the oxidation half-cell is positioned on the left side, while the reduction half-cell is on the right side. The general representation is: Oxidation half-cell | Salt bridge || Reduction half-cell.
04

Fill in the Blank

The correct side for the oxidation half-cell in a cell representation is the left side. So, the answer to fill in the blank is "left". In cell representation, oxidation half-cell is represented on the left.
