The student used an acid-base extraction method to isolate three compounds. In this lab, students will use solvents of different polarity (mobile phases) to determine the optimal separation of the pigments found in spinach extracts.
Mixtures are physical mixtures or additional materials that retain their inherent properties and come together in the form of a reaction, suspension, or colloid. Combinations are materials made from materials or other uniquely styled materials. It can be separated using physical methods. Examples include solutions of salt and water, mixtures of sugar and water, various gases, and air.
The mixture consists of one or more pure materials with different compositions. There are heterogeneous and homogeneous types of mixtures. Dissimilar combinations have visually distinguishable additives, while homogeneous combinations appear uniform throughout. Agglomerates are created by the mixing of two or more distinct substances in the body and can be separated from below into their original substances. A chemical reaction occurs when additional substances combine to form a completely new substance and cannot be separated back into the original substance.
