PART 2 Question 3: Plan an experiment Element KK0512 Problem statement Aim Variables Hypothesis Materials and apparatus Procedures Tabulation of data 20 CHEMISTRY PAPER 3 4541/3
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 21 CHEMISTRY PAPER 3 4541/3
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. 22 CHEMISTRY PAPER 3 4541/3
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 23 CHEMISTRY PAPER 3 4541/3
45 mm 45 mm 59 mm 60 mm 45 mm 50 mm SPM 2006 Question no. 2 PART 2 Plan an experiment to compare one characteristic shown in Diagram 2 for both types of rubber. 24 CHEMISTRY PAPER 3 4541/3
PART 2 SPM 2007 Question no. 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. 25 CHEMISTRY PAPER 3 4541/3
PART 2 SPM 2008 Question no. 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. 26 CHEMISTRY PAPER 3 4541/3
SPM 2009 Question Many possibilities. Please study trial questions from other states and SBP. 1. REACTIVITY OF METAL 2. TITRATION 3. THERMOCHEMISTRY HEAT OF NEUTRALIZATION HEAT OF COMBUSTION 4. RATE OF REACTION EFFECT OF TOTAL SURFACE AREA EFFECT OF TEMPERATURE 27 CHEMISTRY PAPER 3 4541/3
PART 2 MASTERING PAPER 3 : The Analysis Many possibilities. Pay attention to other state trial questions and also SBP. 28
