making salts practical

Step 1 making salts practical:

Put 250cm³ sulphuric acid in a beaker

Step 2 making salts practical:

Add copper carbonate until it stops fizzing

Step 3 making salts practical:

Put funnel and filter inside conical glass and pour in copper/acid mixture

Step 4 making salts practical:

Transfer into evaporating basin on top of a large beaker of water, and heat

Step 5 making salts practical:

Reduce volume by 2/3 or until you can see crystals beginning to form

Step 7 making salts practical:

Leave to evaporate by a window, and you will be left with only crystals

Making salts practical equation:

Copper carbonate+sulphuric acid>copper sulphate+water+carbon dioxide

We leave solutions to evaporate by windows when crystallising because:

It slows down the evaporation process, giving us larger crystals

Safety rules in practical

Hair up, protective gear, no eating/drinking.

Stop heating when

Crystals start to appear

Good quality crystals are

Large

At the end of a practical,

Dry the salts in the oven or with paper towels
