PART 2

If the body of a car is made of iron, it would easily

rust. This is because the iron surface is exposed

to air and water. It is also easily dented in an

accident. Thus, to reduce these problems the

body of the car is made of steel.

Referring to the above situations, design a laboratory

experiment to compare iron andSteel based on one of the following properties:

Hardness or rust resistance

Use the information in Table 3.2 to plan a laboratory

experiment to prepare the esters and describe their

scents.

22

PART 2

Esters can be produced in the laboratory when an alcohol reacts

with a carboxylic acid.

Table 3.2 shows types of alcohol and carboxylic acid used to

produce various esters. These esters have a similar scent to the

esters in fruits.

PART 2

Task 1The copper wire in an electric cable can be easily bent by hand. A

one-cent coin made of an alloy of copper with tin and zinc cannot

be bent easily.

Referring to the situation above, plan a laboratory experiment to

investigate the effect of alloy formation on the hardness of a metal.

Task 2

Buildings in industrial areas more corroded than those in housing

areas. This is because the concentration of acid in rain water ishigher in industrial areas.

Referring to the situation above, plan a laboratory experiment to

investigate the effect of concentration on the rate of reaction

between a named acid and a named metal

Statement 1

Lithium, Li, moves slowly at random on the surface of the waterwith a little fizzing.

The water then turns red litmus paper to blue

26

PART 2

Statement 2

Sodium, Na, moves rapidly at random on the surface of thewater with a hissing sound.

The water then turns red litmus paper to blue.

Statement 3

Potassium, K, moves very rapidly at random on the surface ofthe water. It ignites with a lilac flame with a pop and a hissing

sound. The water then turns red litmus paper to blue.

Plan a laboratory experiment to investigate the reactivity

of lithium, sodium and potassium with water.CHEM ISTRY PAPER 3 4541/3
