Colligative properties of solutions worksheet answers

Suppose that the solution contains ml of each variety of H 2SO4. Total solution is, ml or 0. When the contents of this vessel were pumped into 50 ml vessel, at the same temperature, the pressure of oxygen gets doubled i.

Work in groups on these problems. You should try to answer the questions without accessing the Internet. When a non-volatile solute is dissolved in a volatile solvent, the boiling point increases and the freezing point decreases as though the solute hinders the solvent getting into the vapor phase! Recall that a liquid boils when its vapor pressure is equal to the surrounding pressure If the liquid is in an open container, the surrounding pressure is the atmospheric pressure. Why does the boiling point go up when a solute is dissolved in water? When pure water is heated, the temperature rises until it begins to boil and the temperature remains constant until all the water is evaporated.

Physical properties can be divided into two categories. Extensive properties such as mass and volume depend on the size of the sample. Intensive properties such as density and concentration are characteristic properties of the substance; they do not depend on the size of the sample being studied. This section introduces a third category that is a subset of the intensive properties of a system. This third category, known as colligative properties , can only be applied to solutions. By definition, one of the properties of a solution is a colligative property if it depends only on the ratio of the number of particles of solute and solvent in the solution, not the identity of the solute. Very few of the physical properties of a solution are colligative properties. As an example of this limited set of physical properties, let's consider what happens to the vapor pressure of the solvent when we add a solute to form a solution.

One of the most important applications of colligative properties is that they can be used to determine molar mass. Think about the rate of water flow in both directions. B Non volatile substance has no V. Carousel Next. The osmotic pressure of this solution was found to be 1. NaCl aq. Did you find this document useful? The mole fraction of the gas in the solution is calculated by applying Henry's law. Osmotic Pressure Q6. The freezing point of a solvent depresses as a non-volatile solute is added to a solvent.

If you don't see it, please check your spam folder. Sometimes it can end up there.

B type interaction due to H-bonding. Calculate the freezing and boiling points for a 0. NaCl aq. Hence, the solution shows, negative deviation from Raoult's Law i. Report this Document. This is called reverse osmosis and is commonly used to purify sea water! When you cool a solution, the temperature continues to drop even after the water begins to freeze. When a non-volatile solute is dissolved in a volatile solvent, the boiling point increases and the freezing point decreases as though the solute hinders the solvent getting into the vapor phase! Since you know the mass of solute, you just need to figure out the number of moles to calculate a molar mass. Solutions Numericals Solutions Numericals. What happens the rate of melting? Solvent-solvent interaction and solute-solute interaction are endothermic while solvent- solute interaction is exothermic. Download now.
