Form 4 [extra Quality] - Experiment 4.2 Chemistry

: Test tubes, stoppers, pH meter or universal indicator, Bunsen burner, and spatulas. 3. Experimental Procedure

: Formed by non-metals (Sulphur, Phosphorus, Chlorine). They react with alkalis to form salt and water. experiment 4.2 chemistry form 4

For students sitting for the SPM (Sijil Pelajaran Malaysia) or following the KSSM Chemistry syllabus for Form 4, is a landmark practical. Located in Chapter 4 (The Periodic Table), this experiment bridges theoretical concepts with tangible chemical reactions. : Test tubes, stoppers, pH meter or universal

The primary aim is to study how the chemical properties of oxides change—specifically from basic to amphoteric and finally to acidic—as you go across Period 3. They react with alkalis to form salt and water

: 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
