Question

Suppose you are presented with a clear solution of sodium thiosulfate, \({\bf{N}}{{\bf{a}}_{\bf{2}}}{{\bf{S}}_{\bf{2}}}{{\bf{O}}_{\bf{3}}}\). How could you determine whether the solution is unsaturated, saturated, or supersaturated?

Step-by-Step Solution

Answer

By adding, more solute in the solvent we can find out the nature of solution.               \(\)

Step 1: Saturated and Unsaturated solution

A saturated solution is a solution with a solute that dissolves until it’s far now no longer capable of dissolving anymore, leaving the undissolved substances at the bottom.

An unsaturated solution is a solution with an entire lot of great deal much less solute than the saturated solution that actually dissolves, leaving no substances at the bottom.

Supersaturated is a solution that consists of extra undissolved solute than the saturated answer due to its tendency to crystalize and precipitate.

Step 2: Explanation

To determine the nature of the solution we can add more solute to the solvent if the solute does not dissolve then it is a saturated solution and if there is undissolved solute leftover then it is a supersaturated solution. 

But if the solute is dissolved in the solvent, then it is an unsaturated solution.
