A 0.15 m aqueous solution of a weak acid has a freezing point of -0.31 °C. What is the percent ionization of this weak acid at this concentration? The molal freezing-point-depression constant of water is 1.86 °C/m.

Here are some properties of solutions: Homogeneous mixture: A solution is a homogeneous mixture of two or more substances. The particles of a solution are smaller than 10-9 meters in diameter and are too small to be seen by the naked eye. All components of a solution appear as a single phase. Colligative properties: These are the physical changes that occur when a solute is added to a solvent. Colligative properties are determined by the number of solute particles present, as well as the amount of solvent present. Solubility: This is the ability of a compound to dissolve in water. The...

Here are some properties of solutions:
Homogeneous mixture: A solution is a homogeneous mixture of two or more substances. The particles of a solution are smaller than 10-9 meters in diameter and are too small to be seen by the naked eye. All components of a solution appear as a single phase.
Colligative properties: These are the physical changes that occur when a solute is added to a solvent. Colligative properties are determined by the number of solute particles present, as well as the amount of solvent present.
Solubility: This is the ability of a compound to dissolve in water. The maximum amount of a solute that can be dissolved in a certain amount of solvent at a certain temperature is called the solubility of a solute.
Molarity: This determines some of the solution's properties, including freezing point depression and boiling point elevation.
Stability: Solutions are generally very stable, which means that the solute particles do not separate out on keeping.
