Question

You are working in a commercial laboratory and you are given a sample of a mixture to analyze. It has come from a customer who would like to know the components of the sample. You cannot destroy the components so you know that you will have to use the physical properties of the substances in the mixture to separate them from the others. You have done some work already, and you know that the components of the mixture are sand (SiO2), sugar (sucrose), and iron filings.  You need to find a way to separate these substances and determine the mass percent of each of them in the sample. You have normal laboratory equipment, distilled water, a balance, a drying oven, and filters, as well as glassware and even some hardware. You need to develop a procedure to separate the mixture into its individual components.Mass percent composition of a mixture is found by weighing the mixture, then separating it into its components. The mass of the components then needs to be measured.Similar calculations should be done for each of the components.Your documentation should include the following:A flowchart or decision-tree that outlines how the mixture will be separated.A procedure that shows the steps necessary to separate the mixture into its dry components. This needs to be clear enough for other students to follow.A worksheet which has spaces for the data that will need to be collected during the experimental procedure.Instructions for calculating the mass percent composition for all of the components of the mixture.

Separating Mixture Lab
By using the magnetic properties of iron to remove it from the other components of mixture
Mixture of Sand (SiO2), sugar (sucrose), and iron filings
                                                                                                                            
Sand and Sugar
Iron Fillings
Sugar dissolves in water while sand does not. Add water and drain the solution multiple times (carefully pour out the sugar water).
Sugar Water
Sand and Water
Use heat to remove water from each
Sugar
Sand
       Flow-chart or decision-tree
Procedure
a) Take the sample of a mixture in an evaporating dish which has to be analyzed.
b) By the help of magnetic properties of iron remove it from the other component.

Mass percent composition of a mixture is found by weighing the mixture, then separating it into its components. The mass of the components then needs to be measured.

Similar calculations should be done for each of the components.

Your documentation should include the following:

A flowchart or decision-tree that outlines how the mixture will be separated.

A procedure that shows the steps necessary to separate the mixture into its dry components. This needs to be clear enough for other students to follow.

A worksheet which has spaces for the data that will need to be collected during the experimental procedure.

Instructions for calculating the mass percent composition for all of the components of the mixture.
