The purpose of this lab is to find out how components of a mixture can be separated and analyzed.
Procedure:
The procedure for this lab report is as follows:
1. Mixture is taken, and has to be measured in order to meet the requirements of 2-3g.
2. The mass of the tray is measured and then the scale is zeroed out and the mixture is added to find out the mass of the original mixture.
3. Next, find the mass of the 250mL beaker, zero out the scale, pour the mixture in, and weigh to find the mass. Find the mass of the 100mL beaker as well.
4. In order to separate the iron from the mixture, take a bar magnet inside of a Ziploc bag, and swirl it through the mixture.
5. The iron will stick to the magnet, and lift the magnet out of the mixture. All iron in the mixture should be on the magnet.
6. The iron taken out of the mixture is then measured to find the mass of the retrieved iron.
7. Next, the salt will be separated from the mixture. In order to do this, a ring stand must be set up with an iron ring and a glass funnel. Take a piece of filter paper and fold it as demonstrated by Mrs. Montoney, and place it in the funnel.
8. Place a 250mL beaker under the funnel for the filtered water.
9. Put the remaining mixture in the funnel.
10. Pour some water in a beaker, record the amount of water and pour it in the funnel. The mixture will begin to filter and drain the salt, leaving behind the sand. More water may need to be added depending on if the salt particles are fully desolved or not.
11. The sand has been recovered. Take the filter paper, unfold it, weigh its mass, and place it in the chemical oven to dry before measuring.
12. While the sand is in the chemical oven, take a hot plate, and place the beaker with the filtered salt water on the hot plate. The water will begin to boil, and eventually, the salt will be clearly visible and separated.
13. Once the salt is fully dried out, and no water remains
