As a pot of salt water boils, the water evaporates, leaving behind the salt. Therefore, as the water evaporates, the remaining salt water becomes more concentrated. What happens to the boiling point of the salt water as the water evaporates? a. it remains constant b. it increases with time c. it decreases with time d. cannot be determined from the given information

A traditional way of determining the concentration of alcohol in alcoholic beverages is by measuring thedensity of the solution, since these two characteristics of the solution (density and % alcohol) arerelated. This is a convenient determination method because it is low cost and can be done quickly. Thisis why customs officials sometimes use density measurements to classify alcoholic beverages and spirits.In the stockroom, you will find a variety of reagents including two alcoholic beverages. Design andperform an experiment to classify each of the two alcoholic beverages into one of the following fivecategories of alcohol strength (based on % v/v) defined by the Canadian importation laws:1. Less than 0.5% by volume2. 0.5% - 1.2%3. 1.2% - 7.0%4. 7.0% - 22.9%5. More than 22.9% by volume Pre-Lab Questions1.
