Textbook Problem

(a) Which ion is most easily oxidized to the elemental halogen in acidic solution: F, Cl, Br, or I?

(b) Identify the halide ions that are more easily oxidized in acidic solution than H2O().

(a)

Interpretation Introduction

Interpretation:

It has to be identified which halogen is the most eaisly oxidized in acidic solution F, Cl, Br or I

Concept introduction:

Standard electrode potential

Under certain conditions a cell potential is measured it is called as standard potential (Ecello).

Standard potential (Ecello) can be calculated by the following formula.

Ecello=Ecathodeo-Eanodeo

The Ecello value is positive, the reaction is predicted to be product favoured at equilibrium.

The Ecello value is negative, the reaction is predicted to be reactant favoured at equilibrium.

Electrochemical series:

It is a decreasing order of the reduction potentials. The most positive E0 are placed in the top in the electrochemical series, it has greater tendency for reduction and lower tendency of oxidation. And the most negative E0 values of elements are placed in the bottom of the series.

Explanation

Write the E0 values of the given halogens.

F2(g) + 2e- 2F-(aq)    ; E0=2.87VCl2(g) + 2e- 2Cl-(aq) ; E0=1.36VBr2(l) + 2e- 2Br-(aq)  ; E0=1

(b)

Interpretation Introduction

Interpretation:

The halogens that are easily oxidized in acidic solution than H2O(l) has to be determined.
