Separate a mixture.

Introduction:

Purpose: The purpose with this labboration is to separate the five different substances that are mixed together.

Material and method:

Material:

(9,73g) salt.

(15,46g) sand.

(0,58g) steel wool.

(2,15g) wood dust.

(100 ml) water.

1 spoon. wave. 4 weight papers.

Beaker

Magnet

Execution: Firstly weigh the five substances and decide how many ml of water the mixture will contain. Then mix the salt in the beaker with the water. Stir the mixture with the spoon until the salt has dissolved.

Once the salt is dissolved, put the sand, steel wool and wood dust in the beaker and mix everything together.

For the separation of the substances, put the magnet in the mixture so the steel wool can separate from the mixture, put the steel wool in a separate bowl to let it dry.

Pour the mixture from the beaker to a sifter and let the sifter rest over the beaker while the water runs thru the sifter.

Let that stand for one or two days so that the mixture in the sifter can dry out. Once it is dry you can pour it into a bowl. Then pour the liquid mixture from the beaker into three smaller bowls and put them in a window where the sun can heat them to make the water evaporate.

The solid mixture now contains the sand, wood dust and some salt. Use a coarser sifter to separate the sand and wood dust as good as possible. You should have sand in one bowl (there might be some small bits of wood dust in there to) and wood dust in another. If the dried steel wool got a bit of wood dust on it, try shake it off into the bowl with wood dust. When the water has evaporated the salt is left in the bowls. Put each substance in weight papers again and weigh each substance to see the eventual change off the weight.
