55. A carbonated beverage containing CO2, in which the CO2 is saturated at a certain pressure and temperature. To increase the solubility of CO2 in the beverage, which of the following measures is correct? A. Increase the vapor pressure in the beverage storage tank. B. Reduce the sugar concentration in the beverage. C. Change the beverage’s formula. D. Increase the operating temperature of the beverage storage tank. Answer: A, B. It can be determined that for an ideal solution, Henry’s law applies; B is uncertain. D is definitely incorrect, as higher temperatures result in lower solubility. If multiple choices are allowed, then A should be selected; among B and C, the sugar concentration is part of the formula, so any change in concentration means a change in the formula! So both B and C should be chosen; the answer should be ABC
