Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

In some regions of the southwest United States, the water is very hard. For example, in Las Cruces, New Mexico, the tap water contains about 560 g of dissolved solids per milliliter. Reverse osmosis units are marketed in this area to soften water. A typical unit exerts a pressure of 8.0 atm and can produce 45 L water per day. a. Assuming all of the dissolved solids are MgCO3 and assuming a temperature of 27C, what total volume of water must be processed to produce 45 L pure water? b. Would the same system work for purifying seawater? (Assume seawater is 0.60 M NaCl.)

All of the following statements are correct EXCEPT. A. The vapor pressure increases with increasing temperature because more molecules have sufficient energy to overcome the attractive forces that hold them in the liquid. B. The vapor pressure decreases with increasing strength of intermolecular interactions. C. The pressure at which the rate of molecules evaporating equals the rate of molecules condensing is called the vapor pressure. D. Adding a nonvolatile solute to a liquid increases the vapor pressure. E. The enthalpy of vaporization determines how sensitive the vapor pressure of a substance is to a change in temperature.

You take a sample of water that is at room temperature andin contact with air and put it under a vacuum. Right away,you see bubbles leave the water, but after a little while, thebubbles stop. As you keep applying the vacuum, more bubblesappear. A friend tells you that the first bubbles werewater vapor, and the low pressure had reduced the boilingpoint of water, causing the water to boil. Another friendtells you that the first bubbles were gas molecules from theair (oxygen, nitrogen, and so forth) that were dissolvedin the water. Which friend is mostly likely to be correct?What, then, is responsible for the second batch of bubbles?
