Chem Lab Separation of Mixtures
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

    The slug was used by measuring of different methods, the slugs was placed in a 100ml beaker and weighed then the slug was removed and the beaker was weighed. The measurement of the beaker and slug was recorded, and then the beaker alone was weighed and subtracted from the first measurement giving the weight of the slug by difference. Both results were giving from using first centigram balance and second electronic balance. Both methods of direct weighing and difference by weighing were used when finding the weight of the unknown object. It was done by placing the unknown slug into the beaker and weighing both the slug and the beaker, then removing the slug and weighing the beaker alone. The beaker weight was subtracted from the combined weight measurement in the weight of the unknown slug by difference. The slug was weighed by different method and placed directly on…

    Procedure: I started off by removing the iron using the magnet, and then I weighed all of the iron I obtained from the mixture in a container I already knew the weight of and calculated the net weight of the iron. Next, I took the remaining contents of the mixture and added it with 50 mL of distilled water in the 100 mL beaker, heated it up to separate the sodium chloride and benzoic acid from the insoluble sand, then poured out the benzoic acid and sodium chloride into a separate cup and allowed I to chill in an ice bath for approximately five minutes. I dried up the sand and calculated the net weight for that. I poured the benzoic acid and sodium chloride mixture into a filtered funnel that caught the majority of the benzoic acid and allowed the sodium chloride to drain through to the cup. I allowed the two separate components to dry up and let the water evaporate and then weighed them out and obtained a net weight for the two of them as well as a mixture percentage for all four components.…

    Sources of error include, not letting the sand and benzoic acid not completely cool before weighing, you would get inaccurate results. If the salt was not completely dissolved, you would not get the correct amount in the evaporated solution. If the benzoic acid made it into the sand it would not give you the correct weigh for those values either.…

    A heterogeneous mixture is not uniform throughout. Therefore, separate components of a heterogeneous mixture can be separated by using differences in the components’ physical properties. In this laboratory experiment, I attempted to experimentally verify that the components of a heterogeneous mixture containing salt, sand, and benzoic acid can be separated using the separate components’ solubility properties (ability to dissolve in water). Because it is known that organic compounds (such as benzoic acid) are very soluble in organic solvents, a hexane: ethanol mixture was used to dissolve the acid. Also, because it is known that sodium chloride dissolves in water, water was used to dissolve the NaCl. Along with separating the components of a heterogeneous mixture, the percent recovery of each substance was calculated using the formula: % recovery = (final mass)/(inital mass) x 100. The percent recovery is the amount of substance that was recovered from before the experiment to after the experiment. Overall, in this laboratory experiment, differences in solubility could help to separate the difference components of a heterogeneous mixture of salt, sand, and benzoic acid.…

    First of all, the ball mill was charge with pebbles to approximately 50% of the mill volume and with sand approximately 25% also. Then the ball mill was switch on and operation was done for one hour. Simultaneously the size distribution of the given sand was noted by using the set of sieves. After one hour later the size distribution was noted for the ground sample. Then ball mill was charged again with pebbles to approximately 25% of the mill volume and with sand approximately 25%. After that this sample was grounded for a one hour. After one hour later the size distribution was noted for this ground sample also. All readings were recorded.…
