Lab: Testing unknown solutions for simple carbohydrates, starch, lipids, and proteins.


 * You will be assigned an unknown solution
 * You will be given 6ml of the unknown solution
 * Label your unknown (class pd, initials)
 * your unknown may or may not contain simple carbohydrates, starch, lipids, and proteins
 * You will test your unknown for the presence of simple carbohydrates, starch, lipids, and proteins
 * You will record observations in a data table like the one below:
 * Testing for: || Indicator / Reagent used || Observations for Control (Water) || Observations for unknown || positive or neg for the test ||
 * Simple Carbohydrates ||  ||   ||   ||   ||
 * Complex Carbohydrates ||  ||   ||   ||   ||
 * Protein ||  ||   ||   ||   ||
 * Lipids ||  ||   ||   ||   ||
 * You may test in any order, you will have class time 12/21 and 12/22 to complete the tests.
 * You MUST run a water (control) with each test- this will allow you to observe a neg result- water does not contain carbohydrates, lipids, or proteins.
 * Directions for individual tests are located at the lab stations and online
 * Use the following websites to help you interpret your results- if unsure you may ask Mrs. Murray- after you have checked on your own
