The Discussion of this experiment began with discussing how many materials we use today are actually mixtures of pure substances. The separation of these materials into their pure substances can be quite challenging. When we are discussing separations of a mixture that contains pure substances, it all depends on whether you can separate the substances by physical means. That means, utilizing each substances physical properties such as boiling point, melting point, and magnetism. Separation of a Mixture of Solids

Lab Report Assistant To begin this experiment I got out me scale and little plastic dish and the mixture of substances. I weighed the dish separate and found it to weigh 0.5g. Next I added the mixture to my dish and found the combined weight of the dish and the mixture was 5.5g. I next cut a square sheet of paper and weighed it to find it weighed 1g. I emptied the contents of my dish onto another sheet of paper in a very thin layer. I wrapped the magnet in a sandwich bag and ran it over the mixture to separate the iron. I then carefully pulled the magnet away from the sandwich bag and let the iron fall onto the square piece of paper. I repeated this 3 times to ensure I had all of the iron from my sample. I then weighed the square piece of paper and iron shavings and got a weight of 2.2g. I discarded the iron and moved the remaining mixture into the glass beaker. I added 50mL of distilled water to the mixture. I then lit my burner and moved the stand over the flame and set the beaker with the mixture over the flame. I stirred the mixture several time and when I began to see small bubbles forming I poured the liquid into a paper cup. I then added 20mL of distilled water back into the beaker with the now sand and repeated setting it over the flame until a near boil. I then added this water to the other water in the paper cup and set the sand in the beaker over the...
