Question

The graph shows the solubility curve of an unknown salt. The four points on the diagram represent four solutions of the unknown salt.

T

Answer 1

I can’t see the diagram you’re using. On a solubility curve, a supersaturated solution is any point that lies above the curve (it has more solute dissolved than the equilibrium solubility at that temperature). A point on the curve is saturated; a point below the curve is unsaturated.

So pick the letter that labels the point that lies above the curve. If you post the diagram or describe which letter is above the curve, I’ll pick the correct choice for you.
