a)

Interpretation Introduction

Interpretation:Errors in procedure that cause observed melting point of pure compound to be lower than correct melting point should be determined.

Concept introduction:Melting point is temperature that involves conversion of substance from solid to liquid state. Both liquid and solid phases are present in equilibrium with each other at this temperature.

b)

Interpretation Introduction

Interpretation:Errors in procedure that cause observed melting point of pure compound to be higher than correct melting point should be determined.

Concept introduction:Melting point is temperature that involves conversion of substance from solid to liquid state. Both liquid and solid phases are present in equilibrium with each other at this temperature.

c)

Interpretation Introduction

Interpretation:Errors in procedure that cause observed melting point of pure compound to be broad in range than correct melting point should be determined.

Concept introduction:Melting point is temperature that involves conversion of substance from solid to liquid state. Both liquid and solid phases are present in equilibrium with each other at this temperature.
