1. fold vertical
2. fold the vertical agaij but horizontally
3. pick what side you want to filter through

# data[].attributes.body
Soluble- substance will dissolve in another substance (ex. salt in water)
Insoluble- substance will not dissolve in another substance (ex. water and moth flakes)
Solubility- greatest amount of solute that will dissolve in a given amount of solvent to produce a saturated solution
amount of solute/ amount of solvent = x grams of solute/ 100mL of solvent (cross multiply) (x g/100 mL)

# data[].attributes.body
Intrinsic Property- independent properties that don't change no matter the size of the sample (ex. density, boiling point, melting point etc.)

Ways to test metals
- Magnetic
- Acid test
- Density

# data[].attributes.body
Part of determining substances is discovering whether or not a material is toxic. After perfomriming a series of test we will be able to identify if the substance is toxic.
What is a toxic material?- A material is considered toxic when it causes death or harm by being inhaled, swallowed, or absorbed through the skin. The waste can contain chemicals, heavy metals, radiation, dangerous pathogens, or other toxins.

- Density
- Boiling point
- Flammibility
- Sugar test

If the melting point is over 100 degrees celcius it is no longer micro-melting point it is just melting point

REMINDERS

1.  Heat so that no liquid jumps across to the condensing tube. Don't allow the liquid to climb more than half way up the test tube.

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

3.  There are no liquids with boiling points over 105 oC. Do not allow the thermometer to go higher.

4.  There is at least 10 oC difference between boiling points of any liquids placed in the sludge test.

5.  Only collect and save for further testing the liquids during the plateaus since this is when you get pure liquids in the condensing tube.

6.  Don't forget to add 4-5 boiling chips to the mixture of liquids.

7.  Take temperature readings every minute. Indicate on your data sheet the time when you switched test tubes.

8. Control heat by: 1) Moving up ring stand before starting to heat. 2) Slide test tube up from burner screen. 3) Turn down Bunsen burner with silver gas valve. 4) Slide burner to the side.

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

12.  MAKE SURE THE HOSE IS REMOVED FROM ALL LIQUIDS BEFORE REMOVING THE HEAT.

13.  You may stop when you feel you have enough of your last fraction to do all your tests.

14.  Dissolved solid will affect the plateau temperatures during fractional distillation. Therefore the plateau temperatures during fractional distillation cannot be used to identify the liquids.
