Aim :

Case

:

You are provided with solutions VF3, VF4 and VF5.

The solutions are:

1.0 mol dm3Propanone

1.0 mol dm3Propanal

0.5 mol dm3Propanoic Acid

You are to plan experiments that will enable you to identify the

solution that matches each of

VF3, VF4 and VF5.

You have available the following apparatus:

10 C to 110 C thermometer,

100 cm3beaker, measuring cylinder, and the following reagents

LiAlH4, EDTA, Fehlings Reagent, 2,4 DNPH, and one of your choice.

(a) You are to identify, by the minimum number of practical

steps, which of the solutions contains Propanone

Aim :

Case

:

Caesium nitrate, CsNO3, decomposes on heating.

The decomposition is represented by one of the following equations.

4CsNO3(s) 2Cs2O(s) + 4NO2(g) + O2(g)

2CsNO3(s) 2CsNO2(s) + O2(g)

You are to devise a method of heating the solid

nitrate, collecting the gas given off and measuring its

volume.

From the experimental results you are to determine

hich is the correct e!uation for the decomposition.

Information that may be used to prove your plan and design.

The molar volume of gas, Vm, is 24.0 dm3mol1under room conditions.

Nitrogen dioxide, NO2

, a toxic gas, is soluble in water.

Oxygen, O2, is not soluble in water.

[Ar; Cs, 133.0; N, 14.0; O, 16.0.]
