A saturated solution of compound X in water has a greater concentration than does a saturated solution of compound Y. Does it follow that compound X is also more soluble in water?
A)No, the greater the concentration of a compound in water, the less soluble it is.
B)Yes, compound X is more soluble than is compound Y because a greater concentration in water can be obtained.
C)No, concentration of a solution is not correlated with how soluble that solution is in water.
D)Since both solutions are saturated, it cannot be determined which compound has a greater solubility.

If the concentration of compound X in water is greater than that of compound Y, it means that more of X can dissolve in water at the same temperature and pressure. Therefore, X is more soluble in water than Y. Option A is incorrect because it states an inverse relationship between solubility and concentration which is not always true. Option C is incorrect because there is a direct correlation between solubility and concentration. Option D is incorrect because the relative solubilities of two compounds can be compared even if they are both saturated.
