Colligative properties of solutions worksheet answers

Suppose that the solution contains ml of each variety of H 2SO4. Total solution is, ml or 0.

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?

Practice problems on the colligative properties of solutions covering the freezing point depression, boiling point elevation, vapor pressure, and osmotic pressure of solutions prepared with nonelectrolytes as well as ionic compounds. Calculate the vapor pressure of a solution prepared by adding g glycerin C 3 H 8 O 3 to g of water at Assume that the vapor pressure of pure water at this temperature is How many grams of urea NH 2 2 CO must be added to g of water to prepare a solution with a vapor pressure of The vapor pressure of a solution containing Calculate the vapor pressure of pure benzene at this temperature considering that naphthalene is a nonelectrolyte solid. Determine the mole fraction of the solute in a solution of methanol with a vapor pressure of torr at Determine the molar mass of a nonvolatile, nondissociating compound if adding How many moles of a nonvolatile compound was added to 0.

Colligative properties of solutions worksheet answers

The properties of a solution are different from those of either the pure solute s or solvent. Many solution properties are dependent upon the chemical identity of the solute. Compared to pure water, a solution of hydrogen chloride is more acidic, a solution of ammonia is more basic, a solution of sodium chloride is more dense, and a solution of sucrose is more viscous. There are a few solution properties, however, that depend only upon the total concentration of solute species, regardless of their identities. These colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure. This small set of properties is of central importance to many natural phenomena and technological applications, as will be described in this module. Several units commonly used to express the concentrations of solution components were introduced in an earlier chapter of this text, each providing certain benefits for use in different applications. For example, molarity M is a convenient unit for use in stoichiometric calculations, since it is defined in terms of the molar amounts of solute species:. Because solution volumes vary with temperature, molar concentrations will likewise vary.

C01 14S C01 14S. What is Scribd? Greater the number of solute particles in a solution, higher the extent of elevation in boiling point. CH 11 CH Worksheets: General Chemistry Traditional. Freezing point gets increased. Value of KH decrease when solubility of gas increases Why must intravenous fluids be isotonic with your blood? A J Lecture - 3 Normality Lecture - 3 Normality.

Why does the boiling point go up when a solute is dissolved in water? When a salt solution is heated, the temperature continues to rise even after it begins to boil. Search site Search Search. We can also understand freezing point depression by thinking about the rates of freezing and melting. Why must intravenous fluids be isotonic with your blood? Partnership Liquidation. Note : This equation is solved by assuming that the examinar has taken Mg3 PO4 2 to be completely soluble. This is why we put salt on icy roads! Total solution is, ml or 0. What can you do to get ice to form again?
