Multiple Choice
According to solubility rules, can every solvent dissolve every solute?
A
Solubility is independent of the solvent used.
B
Only polar solvents can dissolve all solutes.
C
Yes, all solvents can dissolve all solutes under standard conditions.
D
No, because solubility depends on the chemical nature of both the solvent and the solute.

Understand the concept of solubility: Solubility refers to the ability of a solute to dissolve in a solvent to form a homogeneous solution at a given temperature and pressure.
Recall the principle 'like dissolves like': Polar solvents tend to dissolve polar solutes, and nonpolar solvents tend to dissolve nonpolar solutes. This is because similar intermolecular forces allow better interaction between solute and solvent molecules.
Recognize that solubility depends on the chemical nature of both the solute and the solvent, including polarity, hydrogen bonding capability, and molecular size.
Note that not all solvents can dissolve all solutes; for example, water (a polar solvent) does not dissolve nonpolar substances like oils well, and nonpolar solvents do not dissolve ionic compounds effectively.
Conclude that solubility is not independent of the solvent used, and it is incorrect to say that all solvents can dissolve all solutes under standard conditions.
