Answer 2

Solids in liquid that do dissolve

Question 3

Question 4

Are are liquids also referred to?

Answer 4

Solvent

Question 5

What is filtration?

Answer 5

Placing insoluble solids into filter paper with tiny holes in a filter funnel to separate the liquid from solids

Question 6

What is crystallisation l?

Answer 6

Place solution into eveLoraring dish and heat it with water baths then ice crystals start to form, leave it to cool then filter it out with funnel and filter paper. To get crystals.

Then leave crystals to dry in warm area

Question 7

What why do crystals form at low temperature?

Answer 7

Solids are more soluble at cold temperature

Question 8

How do you make crystals?(alternative method)

Answer 8

Pour 50cm sulphuric acid into beakers.

Warm gently on tripod and gauze until It begins to steam

Add metal oxide one spatula at a time until I’m excess

Store gently with glass rod

Filter mixture using funnel into conical flask

Transfer metal sulphate solution to evaporating basin

Evaporate half solution and leave rest to stand

-result is metal sulphate salt crystals
