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? ▪️No the greater the concentration of a compound in water, the less soluble it is. ▪️Yes, compound x is more soluble than is compound Y because a greater concentration in water can be obtained ▪️No, concentration of a solution is not correlated with how soluble that solution is in water ▪️Since both solutions are saturated, it cannot be determined which compound has a greater solubility |
Yes, compound X is more soluble than is compound Y because a greater concentration in water can be obtained. |
