Interpretation Introduction

**(a)**

**Interpretation:**

The potential of the electrode with respect to a Ag/AgCl(sat’d) reference electrode after addition of different volumes of Cerium(IV) should be calculated.

**Concept introduction:**

Nernst equation gives the cell potential under non-standard conditions.

E − cell potential

E^{0} − standard cell potential

R − universal gas constant

T − temperature in Kelvin

n − number of electrons transferred

F − Faraday constant

Q − Reaction quotient

Interpretation Introduction

**(b)**

**Interpretation:**

A titration curve should be constructed

**Concept introduction:**

Potentiometric titration is similar to direct redox titrations but in potentiometric titrations no indicator is used. Instead, the potential is measured during the titration to obtain the equivalence point.

Interpretation Introduction

**(c)**

**Interpretation:**

A first and second derivative curve for the data should be generated.

**Concept introduction:**

The first derivative curve of the potentiometric titration is plotted between
