Purpose: To determine and execute the separation of mixture of solids through different means. Examples are magnetisms, evaporation, and filtration.

Observations and Experimental Data:

Data Table 1: Experiment Data

Percent of mixture
Iron filings
1.4 g
31.1 %
28.9 %
Table salt
Benzoic acid
17.8 %


A. How did your proposed procedures or flow charts at the beginning of this experiment compare to the actual procedures of this lab exercise? I would have used the magnet to separate iron fillings as suggested in the lab. But I would have used the filter paper second to separate sand from rest of the solution rather than evaporation.

B. Discuss potential advantages or disadvantages of your proposed procedure compared to the one actually used. Major disadvantages would have been not all the benzoic acid would of passed thru the filter paper which would make our procedure more difficult.

C. How would you explain a sand recovery percentage that is higher than the original sand percentage? Contamination of the other substances left in the sand.

D. What were potential sources of error in this experiment? I feel there are four errors. 1. Not thoroughly moving iron out with magnet.
2. When pouring acid salt mixture into funnel some of the acid crystals stuck to the cup which made it difficult to get all sample out. 3. Some of the benzoic acid might have passed thru the filter paper into the salt water mixture. 4. Not proper dissolving the salt when separating it from the sand leaving salt in the sand mixture.

Final Conclusion: When using various means of separating a mixture (magnetisms, evaporation, and filtration) it is possible to get accurate measurements of each particular material. However there is a high chance of error if care is not taking due to several means of...
