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)]]> 2019-11-15 13:40:32 UTC https://padlet.com/zgsimpso/2r3pm6uleli0/wish/411761361 zgsimpso https://padlet.com/zgsimpso/2r3pm6uleli0/wish/411767896 Intrinsic Property- independent properties that don't change no matter the size of the sample (ex. density, boiling point, melting point etc.)]]> 2019-11-15 13:51:23 UTC https://padlet.com/zgsimpso/2r3pm6uleli0/wish/411767896 zgsimpso https://padlet.com/zgsimpso/2r3pm6uleli0/wish/411768898 Ways to test metals

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.]]> 2019-11-15 16:23:21 UTC https://padlet.com/zgsimpso/2r3pm6uleli0/wish/411885537 zgsimpso https://padlet.com/zgsimpso/2r3pm6uleli0/wish/411909015 - WEAR GOGGLES!!!!!!!!!!!

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.
9. 
   
10.  Don't forget to check for your dissolved solid. There is ONE inside!!!
11. 
    
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.
