A beaker contains an aqueous solution of sodium acetate (NaC2H3O2) of unknown concentration. A few crystals of sodium acetate are added to the beaker. They sink to the bottom of the beaker and remain there unchanged even after further mixing. What can you conclude about the level of saturation of the solution?
A beaker contains an aqueous solution of sodium acetate (NaC2H3O2) of unknown concentration. A few crystals of sodium acetate are added to the beaker. They sink to the bottom of the beaker and remain there unchanged even after further mixing. What can you conclude about the level of saturation of the solution?

The solution is supersaturated.
The solution is saturated.
The solution is unsaturated.
It is not possible to determine the level of saturation because you do not know the concentration of the solution.

Answer #1

Let us anlyse the information:

A beaker contains an aqueous solution of sodium acetate (NaC2H3O2) of unknown concentration. --> we just know a salt is present, no info about solubility

A few crystals of sodium acetate are added to the beaker.

They sink to the bottom of the beaker and remain there unchanged even after further mixing. --> If they sink 100%, then they are not soluble in water, meaning this is already SATURATED

What can you conclude about the level of saturation of the solution?

Since no mor salt can be present in aqueous/solution, then this must be SATURATED

This can't be supersturated since no crystals were formed earlier
