Potassium Manganate(VII) and Water Flashcards
1
Q
Why is potassium maganate(VII) great for this experiment?
A
Because it’s bright purple
2
Q
What happens if you take a beaker of water and place some potassium maganate(VII) at the bottom?
A
The purple colour slowly spreads out to fill the beaker
3
Q
What are the particles of potassium maganate(VII) doing?
A
Diffusing out among the particles of water
4
Q
What causes the purple colour to eventually be evenly spread out throughout the water?
A
The random motion of particles in a liquid
5
Q
What would happen if you were to add more water to the final purple solution?
A
The potassium maganate(VII) particles would spread even further apart and the so,union would be less purple - dilution
