SEPARATION OF MIXTURE

OBJECTIVE:
To separate the components of a mixture based upon physical characteristics of each component within the mixture. Secondly, to determine the mass of each component by using the knowledge of separation techniques.

SAFETY REQUIREMENTS: Do Not Pipette By Mouth Read the Chemical Safety Information Dress Appropriately Identify the Safety Equipment Don't Taste or Sniff Chemicals Don't Casually Dispose of Chemicals Down the Drain

MATERIALS: electronic balance, rubber policemen, stirring rod, beakers, watch glasses, magnet, filter paper, funnel, weight boats, wash bottle, sieve, mixture sample.

PROCEDURE: Separated gravel from the mixture. The masses of weight boat and mixture were determined by using electronic balance. Poured the mixture into the sieve. Held the sieve over a weight boat. The sand and salt past through the holes into the weight boat. The gravel remained behind in the sieve. Shook the sieve back and forth made sure all the sand and salt particles past through the sieve into the weight boat. The masses of gravel with weight boat and left mixture were determined by using electronic balance Separated iron from the mixture. The masses of a magnet and a watch glass were determined by using electronic balance. The magnet was used over the mixture to absorb all iron in the mixture. Put the magnet with iron on the watch glass and the mass of magnet with iron on watch glass was determined by using electronic balance. Separated salt from the mixture. The mass of left mixture with weight boat was determined by using electronic balance. Poured water into the beaker with the sand and salt mixture. Used the stirring rod to stir. The salt began to dissolve in the water. Stirred until all the salt dissolves into the water. The mass of two filter papers was determined by using electronic balance. Folded the filter papers three times and
