Quantitative Methods: Solutions and Dilutions

Part 1 of this series presented types of mixtures that might be prepared and/or encountered in a biological laboratory, and discussed their properties. It discussed the properties of water, the most important biological solvent, and described grades of water with respect to quality. It also introduced basic equipment for solution making, terms and concepts related to formulas, and the concept of the mole. Part 2 will show you how to prepare solutions from common types of formulas and will show you how to carry out dilutions with confidence.
