Question

chemicals used to demonstrate diffusion are :

A) KMnO4
B) CusO4
C) coffee powder
D) All The above

Answer 1

Answer:

D) All of the above

Explanation:

A) KMnO4 introduced with water will collide and the KMnO4 get diffused in water changing the colour of the solution.

B) CuSO4 moves from the higher concentration, i.e., crystal, to lower concentration, i.e., water, and thus show the phenomenon of diffusion

C) Diffusion does occur between water and caffeine in coffee powder

Hence all of these chemicals can be used to conduct the diffusion experiment.
