The ratio of the value of any colligative property for KCl solution to...
The colligative properties of a solution are those properties that depend on the number of solute particles present in the solution, regardless of their identity. These properties include boiling point elevation, freezing point depression, vapor pressure lowering, and osmotic pressure.
The colligative properties are directly proportional to the concentration of the solute particles in the solution. Therefore, the ratio of the value of any colligative property for a KCl solution to that for sugar can be determined by comparing the number of solute particles in each solution.
KCl is an ionic compound that dissociates in water to form K+ and Cl- ions. Each KCl formula unit dissociates into two ions, so the number of solute particles in the KCl solution is twice the number of moles of KCl.
On the other hand, sugar (sucrose) is a covalent compound that does not dissociate into ions when dissolved in water. Therefore, the number of solute particles in a sugar solution is equal to the number of moles of sugar.
From this information, we can determine that the ratio of the number of solute particles in a KCl solution to that in a sugar solution is 2:1. Since colligative properties are directly proportional to the number of solute particles, the ratio of the value of any colligative property for a KCl solution to that for sugar would also be 2:1.
Therefore, the correct answer is option C) 2. The value of any colligative property for a KCl solution is approximately twice the value of that property for a sugar solution.
