# Give the standard line notation for each cell in Exercises 38 and 42.

(a)

Interpretation Introduction

Interpretation:

The equations for different chemical reactions are given. The standard line notation for each cell is to be represented.

Concept introduction:

The shorthand method for the representation of galvanic cell is called line notation for the cell. The anode is written at left hand side while cathode is written right side and they are separated using sing slash or bar to represent the phase change while salt bridge is represented using two slashes or bars between two half cells.

To determine: The standard line notation for the given cell reactions.

The standard line notation for the given equation is represented as,

IO3(aq)+Fe2+(aq)I2(aq)+Fe3+(aq)

Pt/Fe2+,Fe3+//IO3,I2/Pt

The standard line notation for the given equation is represented as,

Zn(s)+Ag+(aq)Zn2+(aq)+Ag(s)

Zn/Zn2+//Ag+/Ag

To determine: The standard line notation for the given cell reaction.

Explanation

The standard line notation for the given cell is represented as,

Pt/Fe2+,Fe3+//IO3,I2/Pt

The given cell reaction is,

IO3(aq)+Fe2+(aq)I2(aq)+Fe3+(aq)

The two half-cell reactions are,

2IO3(a
