Dr. Vicki H Audia
Pelab Questions: Proposed procedure for separation of a mixture: Use physical properties of the 4 substances to separate.
1. Remove iron with magnet
2. Add water to the mixture to melt the benzoic acid and NaCl then filter out sand.
3. Chill the solution and scoop the acid out leaving a salt solution. 4. Boil water away leaving salt.
Purpose: The purpose of this lab is to learn separation techniques using individual physical properties of each substance in the mixture.
Procedure and Data Sheets: Flow Chart. Data Sheets attached. Instructions followed from Lab Manual pages 49-65 …show more content…
Results: See Results Table
A. How did your proposed procedures or flow charts at the beginning of this experiment compare to the actual procedures of this lab exercise? The method was similar to the instructions used in the manual. This student used benzoic acid in an experiment in 151 so I knew that the benzoic acid would crystallize in the cold water and would float.
