Content
Unit –I Chemical Substances – Nature and Behaviour
Chapter-1: Chemical reactions and equations- Chemical equation, Balanced chemical equation,
implications of a balanced chemical equation, types of chemical reactions: combination, decomposition,
displacement, double displacement, precipitation, endothermic exothermic reactions, oxidation and
reduction.
Practical: Performing and observing the following reactions and classifying them into:
a) Combination reaction b) Decomposition reaction
c) Displacement reaction d) Double displacement reaction
(i) Action of water on Quick lime(calcium oxide)
(ii) Action of heat on Ferrous sulphate crystals
(iii) Iron nails kept in Copper sulphate solution
(iv) Reaction between Sodium sulphate and Barium chloride solutions
Chapter-2: Acids, Bases and Salts-Their definitions in terms of furnishing of H+ and OH– ions, General
properties, examples and uses, neutralization, concept of pH scale (Definition relating to logarithm not
required), importance of pH in everyday life; preparation and uses of Sodium Hydroxide, Bleaching powder,
Baking soda, Washing soda and Plaster of Paris.
Practical : A)Finding the pH of the following samples by using pH paper / universal Indicator:
a) Dilute Hydrochloric acid b) Dilute NaOH solution
c) Dilute Ethanoic Acid Solution d) Lemon juice
e) Water f) Dilute hydrogen carbonate solution
B) Studying the properties of acids and bases (HCl & NaOH) by their reaction with:
a) Litmus solution (Blue/Red)
b) Zinc metal
c) Solid sodium carbonate
Chapter-3: Metals and Non-Metals- Properties of metals and non-metals; Reactivity series; Formation and
properties of ionic compounds; Basic metallurgical processes; Corrosion and its prevention
Practical : Observing the action of Zn, Fe, Cu and Al metals on the following salt solutions:
a) ZnSO4 (aq) (b) FeSO4 (aq) (c) CuSO4 (aq) (d) Al2(SO4)3 (aq)
Arranging Zn, Fe, Cu and Al (metals) in the decreasing order of reactivity based on the above result.
Unit II: World of Living
Chapter-5: Life processes- "living being". Basic concept of nutrition, respiration, transport and excretion in
plants and animals.
Practical: Preparing a temporary mount of a leaf peel to show stomata.
Practical: Experimentally show that carbon dioxide is given out during respiration.
