This is done to dilute a very  potent drug powder. An aliquot of the mixture contained the desired quantity of the substance at a certain amount to maintain the accuracy of the active component of the emulsion. Emulsions are mixture of two liquids that are immiscble. Fine dispersion of minute droplets can be observed in one liquid when this happens. Emulsions are part of  general class with 2 phase system called colloids.

  • No of protons=No of electrons=15
<h3>Mass no:-No of neutrons+No of protons </h3>

\\ \tt\longmapsto 15+16=31

Now

  • It has atomic no 15 hence its Phosphorus(P)

Electronic configuration:-

\\ \tt\longmapsto 1s^22s^22p^63s^23p^3.

  • Valency=3

Chloride formula:-

\\ \tt\longmapsto XCl_3

or.

\\ \tt\longmapsto PCl_3
