Samira A. Ben Mussa et al /Int.J. PharmTech Res.2009,1(3) 600 1. First, the concentration of the chloride in the sample was determined, the reading of chloride was divided by 10 and an amount of silver sulfate equivalent to the amount of chloride was added. 2. (2

Reactions and Appliions of Coordination Compounds | …

The chelate effect describes the enhanced affinity of chelating ligands for a metal ion compared to the affinity of a collection of similar nonchelating (monodentate) ligands for the same metal. Consider the two equilibria, in aqueous solution, between the copper (II) ion (Cu 2+ ) and ethylenediamine (en) on the one hand and methylamine (CH 3 NH 2 (MeNH 2 )) on the other.

Most calcium and magnesium supplements contain a ratio of two parts calcium to one part magnesium. The logic behind this ratio is based on the relative amounts of these nutrients used in the body. But in order to determine how much we might need to take as a supplement, we should consider how much of these nutrients we are getting in our food and how they are stored and recycled in the body.
