NaCl, table salt, and ammonium chloride will both dissolve in water. Sand is only sparingly soluble in water. If you want to further separate ammonium chloride from sodium chloride, you will need to dry the resulting solution. The sodium chloride will precipitate out first. The ammonium chloride will remain in the supernatant and can be poured off leaving the sodium chloride crystals behind.
On heating it sublimes and the vapor easily crystallizes to a solid again. Salt has a much higher melting point and sand extreemly high.
Your mom! hahaha jk, its the communitive property
They are both difficult to separate because both of these have very little difference in their boiling points.This makes separating them difficult. Hence, they are separated by fractional distillation
Malleability
density
freezing point.........................
it is acidic!
amphipathic molecules
Conductor
The property of a salt that enables it to absorb water from the atmosphere is known as hygroscopicity.
Primarily it is its low boiling point and hence volatility that enables smell/aroma. There are other factors too.
cohesion and adhesion
