Question

Let us divide the class into groups A, B, C and D. • Group A takes a beaker containing 50 mL of water and one spatula full of copper sulphate powder. Group B takes 50 mL of water and two spatula full of copper sulphate powder in a beaker. • Groups C and D can take different amounts of copper sulphate and potassium permanganate or common salt (sodium chloride) and mix the given components to form a mixture. • Report the observations on the uniformity in colour and texture. • Groups A and B have obtained a mixture which has a uniform composition throughout. Such mixtures are called homogeneous mixtures or solutions. Some other examples of such mixtures are: (i) salt dissolved in water and (ii) sugar dissolved in water. Compare the colour of the solutions of the two groups. Though both the groups have obtained copper sulphate solution but the intensity of colour of the solutions is different. This shows that a homogeneous mixture can have a variable composition. • Groups C and D

Answer 1

Answer:

we have to divide this because the group of abcd=. group a breaker containing 50ml of water and one spatula full of copper sulphate power.

group b takes 50ml of water.

Explanation:

group a and is the best answer
