The given apparatus shows the simple distillation of a table salt solution. In which part of the apparatus is salt collected at the end of the experiment? (A) The distilling flask, (B) the glass beaker, (C) the condenser, (D) the conical flask.

Simple distillation is a type of distillation in which the most volatile component is separated from the mixture by heating and then condensing and collecting the vapor. In this problem, the mixture being separated is a table salt solution. The solution is composed of sodium chloride dissolved in water. The boiling point of liquid water is substantially lower than that of sodium chloride. Therefore, water is the most volatile component in the mixture and will boil first.

At the beginning of the experiment, the table salt solution is found in the distilling flask. The solution is heated using a Bunsen burner. And when a temperature of 100 degrees Celsius is reached, the water in the mixture boils and turns into a vapor. As heating continues, the water vapor rises up and out of the flask until it reaches the condenser, at which point the water vapor is cooled and converted into liquid water. The liquid water is then collected in a conical flask. The distillation will be complete when all of the water in the distilling flask has been boiled away, condensed, and collected in the conical flask. Pure solid sodium chloride salt will be left behind in the distilling flask.

So, in which part of the apparatus is salt collected at the end of the experiment? The answer is the distilling flask, or answer choice (A).
