For each of the following questions, assume that all measurements are made in 10-cm polarimeter sample containers. (a) A 10-mL solution of 0.4 g of optically active 2-butanol in water displays an optical rotation of 20.568. What is its specific rotation? (b) The specific rotation of sucrose (common sugar) is 166.4. What would be the observed optical rotation of such a solution containing 3 g of sucrose? (c) A solution of pure (S)-2-bromobutane in ethanol is found to have an observed a 5 57.38. If [a] for (S)-2-bromobutane is 23.1, what is the concentration of the solution?

Which of the following best describes why magnesium hydroxide, found in milk of magnesia, is soluble in acidic solution? O According to Le Chatelier's principle, the acid will react with hydroxide ions in the solution, forming water and thereby decreasing the concentration of hydroxide ions in solution causing more magnesium hydroxide to dissolve. O Magnesium hydroxide does not dissolve in acidic solutions. O According to Le Chatelier's principle, the acid will react with magnesium ions in the solution, forming magnesium hydride and causing more magnesium hydroxide to dissolve.
