PART 2
SPM 2003 Question no. 3
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 and
Steel based on one of the following properties:
Hardness or rust resistance
No diagram

PART 2
SPM 2004 Question no. 3
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.
Use the information in Table 3.2 to plan a laboratory
experiment to prepare the esters and describe their
scents.

PART 2
SPM 2005 Question no. 3
Task 1
The 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 is
higher 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

PART 2
Identify the factor that influences the differences in
the voltage.
Plan a laboratory experiment to construct an
electrochemical cell to determine one factor that
influences the differences in the voltage.

SPM 2008 Question no. 2
PART 2
Statement 1
Lithium, Li, moves slowly at random on the surface of the water
with a little fizzing.
The water then turns red litmus paper to blue
Statement 2
Sodium, Na, moves rapidly at random on the surface of the
water 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 of
the 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.
