***What to do Once Given Sludge (Detailed)***

# data[].attributes.body
1. Pour the sludge into a large a medium beaker. Once in, take out the solids such as metals, plastics.

2. Take what remains of the sludge and put it through a filtration tube with paper. Any insoluble powders should get caught on the wet filtration paper.

3. One partner starts FRACTIONAL DISTILLATION, only pouring 10mL of sludge into a LARGE test tube.

4. The other partner separates the plastics and metals into different categories to prepare for identification, which will be done on the third day, after all testing is complete.

5. The same partner then proceeds to work on the separation of the insoluble powders.

ONLY use a SMALL piece of the plastic to put into the flame!!

--If you heat too slowly, you will not complete fractional distillation in the one class period.

--Don't forget to check for your dissolved solid. There is ONE inside!!!

--Make sure partner and I are both working on different tests.

--In the end, it's just a test. You got this :)

--A SOLUBLE (DISSOLVED) SOLID AND LIQUID: Evaporate the Liquid using an Evaporating Dish

--AN INSOLUBLE (NON-DISSOLVED) SOLID AND LIQUID: Use a funnel and filter paper.

--A SOLUBLE (DISSOLVED) SOLID AND AN INSOLUBLE (NON-DISSOLVED) SOLID: Add the solids to water. Filter the insoluble solid, then evaporate the soluble solid.

--2 LIQUIDS: Fractional Distillation

--MAGNETIC AND NON-MAGNETIC MATERIAL: Move a magnet through the mixture, collecting any magnetic material.

Whether or not a Solute (Powder) dissolves into a Solvent (Liquid).

The Solute on the left is Soluble, while the Solute on the right is Insoluble.

The method used to purify liquids.

Wait around 5ish degrees for the plateau to end, then change test tubes.

**NEED AT LEAST 5 ML OF PURE LIQUID TO PROCEED**

**PLATEAU = PURE**

Sludge is a mixture of different substances. Some of which include, Metals, Non-Metals (Plastics), Dissolved and Non-Dissolved Powders, and Liquids.
