To determine

To Choose: The correct option.

Answer to Problem 5STP

Option B

Explanation of Solution

Solubility increases with increase in temperature. Out of sodium bicarbonate, sodium carbonate, sodium hydroxide and sucrose, sucrose has higher solubility at temperature at $20°C$ .

Conclusion:

Sucrose dissolves in water because energy is given off when the slightly polar sucrose molecule form intermolecular bonds with the polar water molecules. The weak bond between the solute and solvent compensate for the energy needed to disrupt the structure of both the pure solute and solvent.
