Calculating Liquid Chemical Dilutions
Found 3 free book(s)How to Make Simple Solutions and Dilutions
www.penguinprof.comsolutions, or perhaps due to limited availability of liquid materials (some chemicals are very expensive and are only sold and used in small quantities, e.g., micrograms), or to limit the amount of chemical waste. The formula below is a quick approach to calculating such dilutions where:
Molecular Formula: Example

McFARLAND STANDARD - Dalynn
www.dalynn.comthe approximate number of bacteria in a liquid suspension by comparing the turbidity of the test suspension with that of the McFarland Standard. A McFarland Standard is a chemical solution of barium chloride and sulfuric acid; the reaction between these two chemicals results in the production of a fine precipitate, barium sulfate.
