# How is a saturated solution of sodium nitrate prepared?

Sep 17, 2016

With difficulty inasmuch as sodium nitrate is exceptionally soluble in water.

#### Explanation:

A saturated solution is described when the amount of solute in solution is equal to that amount that would be in equilibrium with undissolved solute. At laboratory temperatures, this might be as much or more as 100 g of solute in 100 mL of solution.

This site quotes a solubility of $91.2 \cdot g \cdot 100 \cdot m {L}^{-} 1$ at $25$ ""^@C.
