How to Read the Concentration Ratio
This comprehensive overview delves into the intricate realm of reading concentration ratio, presenting a clear understanding of weight/weight (w/w) and weight/volume (w/v) units. By offering an analogy that juxtaposes the additive nature of mass with the nuanced behavior of liquids, it illuminates how combining equal volumes of liquids may yield unexpected results due to density disparities. The discourse delves into concentration units—percentages, parts per million (ppm), and parts per billion (ppb)—their conversions, and the pragmatic selection of the appropriate unit
