The reason we should store phosphorous in water is because it will ignite on contact with air
The sample must be sufficiently soluble (fig. 2) to yield an NMR spectrum. For 1H and 1H observed NMR, it is recommended to dissolve between 2 and 10 mg in between 0.6 and 1 mL of solvent so that the sample depth is at least 4.5 cm in the tube (fig. 3).
Substances that posses an excess it greater amount of hydroxide ions are considered basic, or alkali like in solution. They would thus showcase properties of a basic substance.
