Experimental wet chemistry and salt synthesis pathways define Grade 10 Chemistry for Term 3, organising 45 laboratory-intensive periods across 10 pages. Practical tasks link to pages 120 through 185 of the Chemistry Learner’s Book and centre on the Physical Chemistry strand.
- Acids and Bases: testing household solutions with litmus and Universal Indicator, tracking hydrogen and carbon dioxide gas evolution, observing neutralisation thermal changes, and testing electrical conductivity using graphite electrodes in weeks 1 to 3.
- Introduction to Salts: applying general solubility rules, synthesising crystals via titration and precipitation, contrasting deliquescent, hygroscopic, and efflorescent substances, and calculating percentage crystallization yields during weeks 3 to 8.
- Environmental and Practical Review: examining eutrophication from excessive nitrate fertilizer runoff and testing unidentified salt stations with barium nitrate and silver nitrate in weeks 6 through 9.
Learners handle burettes, pipettes, evaporating dishes, and chemical reagent sets while observing laboratory hazard symbols and waste neutralisation protocols.
