Separation Technique

Separation Filtering etc

Evaporating separates a dissolved solid
Magnetism separates a mixture of solids containing either iron or cobalt or nickel
Chromatography separates a mixture of coloured substances
Filtering separates a mixture of solid and liquid
Distilling separates a mixture of different boiling points
2 steps of Distillation evaporation then condensation
4 steps of separating iron, sand and salt 1. magnetic 4 iron; 2. Dissolve and filter 4 Sand; 3. Dissolve 4 salt to separate; 4. Evaporate 4 salt
Magnetism explained to separate iron filings from sand. Iron is magnetic and will be attracted to magnet / sand is not attracted to the magnet.
Dissolving explained salt in water. Salt will dissolve in water / sand will not dissolve in water.
Filtering explained sand from salt water. The salt water is a solution and will go through the filter paper / the sand will get stopped by the filter paper / sand particles too large to go through the paper.
Evaporation explained the water from the salt. The water will evaporate off, leaving the salt.
Decanting the sawdust and salt water from the sand. Sand is heavy and will stay at the bottom / the light saw dust will pour off with the water.
Distillation the water from the salt. The water will evaporate off, leaving the salt, then the water will condense again
