Question
Chapter 4.4, Problem 6E
Interpretation Introduction
Interpretation: Alignment of column of fractional distillation apparatus in vertical position should be explained.
Concept introduction: Fractional distillation is separation technique that separates various fractions of components in mixture. This process is based on vaporization of one or more fractions or parts of mixture. It is used to separate components of mixture that have difference in boiling points less than

Group of answer choices (a) Gas that was trapped at the top of the bottle between the cap and the surface of the liquid escapes immediately and 'draws' liquid soda as it escapes, creating the illusion of bubbling. (b) The act of opening the bottle 'dislodges' tiny, nearly invisible gas bubbles that were clinging to the side of the container. They quickly condense into larger bubbles and escape. (c) Warm air from outside the bottle heats the soda, decreasing the solubility of the CO2 in the soda and causing it to bubble out. (d) When the bottle is opened, the pressure of CO2 gas above the liquid rapidly drops, which significantly decreases the solubility of CO2 in the soda, causing it to bubble out. (e) H2CO3 in the soda reacts with water vapor in the air, forming CO2 that quickly bubbles out.arrow_forwardWhen performing a recrystallization of an impure solid, why is it important to allow the heated solution to cool slowly?
