PHOSPHORUS
Phosphorus is an important element for both plants and animals. It is
contained in the nucleus of the plant cell, which controls cell division
and growth, and has an important role in energy storage and chemical
transfer within the plant. Phosphorus is also important to fruiting and
seed production.
Phosphorus reacts with molybdate in *VM Phosphate Reagent to form a
phospho-molybdate compound. Reduction with stannous chloride in the
*Reducing Reagent produces a molybdenum blue color. The resulting
color is matched to a color standard to determine the phosphorus
concentration.
