You need your lab notebook!!. A note on assignments. Late homework is worth 50%. I will not stamp the date on it. BE ORGANIZED!! Keep your notebooks in one place (on your shelf). Keep a separate notebook for each class.
Separation of a mixture
(removes water from a sample)
Drying oven (removes water from a sample quickly)
Spatula (for moving powdered chemicals from their containers)
Record a qualitative description.
How would you separate this mixture (and record the mass of each compound after separation)?
Process of Separation
Residue – manganese dioxide
Reacts with HCl acid, turns moist KI paper blue
Solute – sodium chloride
Reacts with AgNO3 solution to form white precipitate
Add to your procedure to fix these problems!!
