Separation Of Mixture Lab
Experiment 1 Separation of Mixtures
Summary of Principles: Most of the materials we encounter in everyday life are not pure substances. Many materials such as sand are formed from physical combination of various substances, and are called mixtures. Mixtures can be classified into homogeneous and heterogeneous. The purpose of this lab is to learn how to separate individual components from a mixture through decantation, filtration, distillation, and crystallization.

Once the iron filings stick to the magnet, lift the magnet with the iron filings and place the end with the filings inside a beaker.

Separation of a Mixture of sand and copper salt

• In a test tube stir 2 g of sand copper and 5ml of water.
• In a hot plate heat up the beaker with the supernatant until water is evaporated.

Separation of a Mixture of sand, calcium, and copper
• In a beaker add 3g of sand, calcium, copper and deionized water and stir until copper dissolves.
• Put a filter paper into a funnel, then pour the mixture into the filtering apparatus letting it drop into a beaker.
• Transfer the solid from the filter paper into a beaker and add 10mL 1 M HCL and stir the mixture until the white solid dissolves.
Safety Precautions: When adding 1 M HCL make sure to wear gloves to protect your hands from the acid.
Results and Discussion:
1. Weight of 50ml beaker + solid = 52.2g
2. Weight of 50ml beaker = 50.3g
3. Weight of solid [(1)-(2)] = 2
4. Weight of solid in the mixture
5. Absolute error [(3)-(4)] =
