can sm1 help me in chem experiments plz...................?

Question

Project I
Study the rates of diffusion of K2Cr2O7 (Potassium) at different temperatures:

At room temperature:
Procedure – Take two glass containers and graduate them. Now place 1 g of crystal of K2Cr2O7 at the bottom of one container and record the level of coloured solution at regular intervals of time as follows:

Time in hr. Level of coloured solution Rate of diffusion=
0.25
0.50
0.75
1.00
Total Time = 1.00 hr
Average rate of diffusion = ________ ml/hr

Repeat the above experiment with hot water say water at 600C

Project II
Study the effect of particle(crystals) size on rate of diffusion of solid in liquid
Procedure – Take 3 different size crystals of KMnO4 of almost same weight in 100 ml water and record the observations as above.
State the scientific reason for your observations

Answer 1

What is your question here? Without your experimental data, nobody can even begin to give you any assistance . . .

But I will give you a hint -- the hot water should show more rapid diffusion, because of the increased molecular motion of water at higher temperatures (say 60°C), which in turn will cause the dissolved molecules of potassium chromate to disperse more rapidly.

Smaller crystals of potassium permanganate will dissolve more rapidly, and that will also influence (slighty) the diffusion rate.

Answer 2

do the experiments, tell us what u saw, we will gladly help you understand why you saw it!

Answer 3

help ,its blasted.
