conical flasks, stopwatch, measuring cylinders, and a white paper marked with a large ‘X’. Materials: sodium thiosulphate solution, 1.0 sulphuric acid, and distilled water. The Procedure Prepare the 'X':
: A small amount of each oxide is added to a test tube containing distilled water. The mixture is shaken, and the pH is measured using a pH meter or universal indicator. experiment 4.2 chemistry form 4
: As we move across Period 3 from sodium to chlorine, the oxides of elements change from basic to amphoteric and then to acidic . Variables : Manipulated : Types of oxides (e.g., Na2Ocap N a sub 2 cap O MgOcap M g cap O Al2O3cap A l sub 2 cap O sub 3 SiO2cap S i cap O sub 2 P4O10cap P sub 4 cap O sub 10 SO2cap S cap O sub 2 Cl2O7cap C l sub 2 cap O sub 7 conical flasks, stopwatch, measuring cylinders, and a white
Here’s a clear and engaging post about based on the typical Malaysian SPM curriculum (KSSM). The experiment usually focuses on Periodic Table – Reactivity of Group 1 (Alkali Metals) or Group 17 (Halogens) . The mixture is shaken, and the pH is

Place a conical flask on a white paper marked with a black cross. The Base Mixture: sodium thiosulphate into the flask. Start the Reaction: Quickly add 5 of sulphuric acid and start the stopwatch immediately. The Observation:
After conducting the experiment, students should analyze their results and discuss the findings.
