Question

§ Take two glasses/beakers filled with water.§ Put a drop of blue or red ink slowly and carefully along the sides of the first beaker and honey in the same way in the second beaker.§ Leave them undisturbed in your house or in a corner in the class.§ Record your observations.§ What do you observe immediately after adding the ink drop?§ What do you observe immediately after adding a drop of honey?§ How many hours or days does it take for the colour of ink to spread evenly throughout the water?

Answer 1

In these activity we observe that water is a aqueous solutions and got dissolved in water after some time for keeping undisturbed but honey takes a longer time and it does not get completely distilled in water. We observe in case of ink drop that it takes less time as compared to honey and it get completely dissolved changing water colour.We observe in honey that it takes very much time and does not get fully dissolved. The ink only takes 10 to 15 hours to get completely dissolved.

Answer 2

Immediately after adding the ink drop we boserve that the ink uniformly mixes with water within seconds.

after adding a drop of honey we observe that it does not mixes and goes at the bottom of water.

time taken is 10 seconds.
