Question

Is PRACTICALS

Practicals should be conducted alongside the concepts taught in theory classes.

List of Experiments:

1. Studying the properties of acids and bases (HCl & NaOH) by their reaction with: (Unit - I)

(a) Litmus solution (Blue/Red)

(b) Zinc metal

(c) Solid sodium carbonate

2. Performing and observing the following reactions and classifying them into: (Unit - I)

A. Combination reaction

B. Decomposition reaction

C. Displacement reaction

D. Double displacement reaction

            (i) Action of water on quick lime

            (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

3. Observing the action of Zn, Fe, Cu and Al metals on the following salt solutions: (Unit - I)

(i) ZnSO4 (aq)

(ii) FeSO4 (aq)

(iii) CuSO4 (aq)

(iv) Al2(SO4)3 (aq)

Arranging Zn, Fe, Cu and Al (metals) in the decreasing order of reactivity based on the above result.

4. Studying the dependence of potential difference (V) across a resistor on the current (I) passing through it and determine its resistance. Also plotting a graph between V and I. (Unit - IV)

5. Experimentally show that carbon dioxide is given out during respiration. (Unit - II)

6. Determination of the focal length of: (Unit - III)

(i) Concave mirror

(ii) Convex lens

 by obtaining the image of a distant object.

7. Tracing the path of a ray of light passing through a rectangular glass slab for different angles of incidence. Measure the angle of incidence, angle of refraction, angle of emergence and interpret the result. (Unit - III)

8. Studying (a) binary fission in Amoeba, and (b) budding in yeast and Hydra with the help of prepared slides. (Unit - II)

9. Tracing the path of the rays of light through a glass prism. (Unit - III)
