Solutions 1. Identify the solvent and solute(s) in each of the following solutions. Note that there may be more than one solute in a solution. A 20 g of calcium chloride CaCl2 dissolved in 100 g of water. Solvent Solute(s) B Air which contains 20.95% oxygen, 0.93% argon, 78.09% nitrogen and 0.04% carbon dioxide. Solvent Solute(s) C Rubbing alcohol which consists of 70% isopropyl alcohol and 30% water. Solvent Solute(s) D Alloy 7705 which consist of 6% zinc, 2.3% magnesium, 1.5% copper, 88% aluminum and small amounts of other elements. Solvent Solute(s) 2. Purified water does not conduct electricity. It can be prepared by reverse osmosis, distillation or passage through deionizing resin beds. One of the tests for the quality of purified water is to test its conductivity. Does tap water conduct electricity? Can you provide an explanation regarding the difference in conductivity observed between tap water and purified water?
3. Classify each of the following as a non-electrolyte, weak elec electrolyte. Substance Classification A nickel(II) nitrate NI(NO3)2 sucrose C12H22011 methyl alcohol CH3OH acetic acid CH3COOH E potassium bromide KBr 4. Write the chemical equations for solution formation in water for each of the following substances. Include the appropriate phase labels and arrows, or in your equations. Equation A Substance magnesium bromide MgBr2(5) B fructose C6H12O6(s) C ison isopropyl alcohol CzH;OH(1) D lactic acid C3H6O3(s) 5. Would you expect to observe a higher concentration of dissolved oxygen in a lake close to sea level or in a mountain lake? Assume the water temperature is the same. Provide an explanation and reference Henry's law and how altitude affects the atmospheric pressure.
