Objective. To develop a method to effectively separate four compounds commonly found in over-the-counter pain medications. You will use your optimized method to determine the composition of a commercially available product. Background. What is stuff made of? This fundamental question, even when clumsily worded, is a cornerstone of the science of chemistry and provides us with the context of our first lab. As you will see over the term (or terms, if you continue with the subject), there are many different ways this question can be answered. For now, we will have to be content with the following: most matter that we encounter on a routine basis is composed of fundamental particles called molecules, of which millions of different types are known. Each molecule of the same type is identical to others of its kind and distinct from those of other kinds. A large collection of identical molecules is called a compound, such as water, sucrose (aka table sugar), and linoleic acid, the focus of mu
