Question

A large crystal of potassium manganate(VII) was
placed in the bottom of a beaker of cold water, and
left for several hours.
a) Describe what would be seen:
1. after five minutes

Answer 1

Answer:

After 5 minutes the crystals colour covers the bottom. and eventually the water turns purple.If you will take hot water it will diffuse faster.

Explanation:

Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature.So  the water is cold so the diffusion will occur slowly.Diffusion occurs when particles move from an area of high concentration to an area of low concentration. The factors affecting rate of diffusion are: concentration, temperature, mass of the particle and properties of the solvent in which diffusion occurs. Faster movement equals faster diffusion.

I hope this answer help you.
