Tutorial 4 SOLUTION STOICHIOMETRY

If volume and concentration of both reactant solutions are given then you are dealing with a limiting reagent problem. The first step is to find the moles of each reactant from the volume and concentration of the solution. Once moles are found the process is the same as shown in Tutorial 3, p T-23.

Ecological Soil Screening Levels for Manganese

Manganese is essential in plant nutrition for the oxidation-reduction process. Specifically, manganese participates in the oxygen-evolving system of photosynthesis and in the photosynthetic electron transport system. In the soluble form, manganese is easily taken up from soils by plants and is rapidly translocated throughout the plant.
