Question

odnl n ih Da ou would observe as the temperature is raised. The following data are available to you from a handbook of chemistry is disolved in 100 mL of water in one both are saturated solutions; some solid remi is dissolved in 100 mL of water in one beaker, and some Laso, is 10 °C, and both are saturated 3 Some lihium chiloride, LiCL, 40"C 745 898 LO Colligative Colligative Properties of solutions, particles in a solution and not on their identity." are properties that depend on the relative numbers of solute and solvent For instance: When a non-volatile solute is dissolved in a volatile solvent, the boiling point elevates and the freezing point depresses (as though the solute hinders the solvent from getting into its liquid phase, thereby changing its properties) 1. Recall that a liquid boils when its vapor pressure is equal to the surrounding pressure (If the liquid is in an a solute is dissolved in water? open container, the surrounding pressure is the atmospheric pressure). Why does the boiling point go up when 2. As we have learned, the phase change of pure substances is isothermal. As expected, when pure water is heated, the temperature rises until it begins to boil and the temperature remains constant until all the water has evaporated. When a salt solution is heated, the temperature continues to rise even after it begins to boil. Why

Explanation / Answer

According to chegg rules we have to answer only first one problem

Solubility:

When the maximum amount of solute is dissolve in the solvent is called solubility. On the basic of solubility the solution are following types:

Saturate solution:

A solution which contains the maximum amount of dissolved solute at the equilibrium is called saturated solution.

Un-saturate solution:

A solution which contains lesser amount of solute as compare to saturated solution. It will be able to dissolver more solute.

Super -Saturate solution:

A solution which contains the more dissolved amount of solute as compare to saturated solution.

Given that the solubility of LiCl and Li2SO4 as follows:

compound

10 C

40 C

Li2SO4

35.5

33.7

LiCl

74.5

88.8

When the saturated solution of both compound is heated then Li2SO4 will comes out from water because it solubility decreases with increase temperature.

35.5-33.7 = 1.8 g

Around 1.8 g Li2SO4 was predicated out.

On the other hand LiCl will be more soluble on heating the solution.
