Lab Title: Separation of a mixture. Date:________ Block:________
Name of lab Partner:_______________________________
You are going to separate a mixture today in lab working with a partner.
PURPOSE OF LAB:
1. To separate a mixture of sand, sodium chloride, iron filings, and marbles (or some
other large object).
2. To determine the mass of each substance.
3. To calculate the percent error comparing total amount of substance to begin with
and the amount of substance recovered.
Pre-lab Discussion:
The following properties of each substance are listed below. You and your partner are
to spend some time in discussion and map out a strategy of how each substance will
be separated and then how you will determine the mass of each substance.
SUBSTANCE
Soluble in water? Magnetic?
Large or small
particles
Sand (SiO2)
sodium chloride
Iron
Marbles or other
object
Equipment:
-List any equipment you use in this space. Make sure you use the proper names for
the pieces of equipment used. If you need a reference, use the laminated sheet
provided by the instructor.
Materials: Sample of mixture containing iron, sodium chloride, sand, and pennies,
tap water, distilled water.
Determine the initial mass of the mixture: ________________________
1
Draw a qualitative scheme to demonstrate how you separated each component
from the mixture. Determine the mass of each component and place the mass
next to the final box.
