Answer:
b) The boiling point of the solution is always greater than the boiling point of the pure solvent.
Explanation:
Hello,
In this case, when we add a nonvolatile solute to a volatile solvent which has a relatively low boiling point, we can evidence the increase of the boiling point of the resulting solution as more energy must be supplied to take the molecules from liquid to gas. This fact matches with the boiling point elevation colligative property due to the solute's addition, which states that the boiling point of the solution is always greater than the boiling point of the pure solvent, therefore, answer is b).

Answer: Option (d) is the correct answer.
Explanation:
It is known that polyethene which have high density and these are generally safe plastics which does not transfer any chemicals to food ingredients. In most of the industries, these type of plastics have large application because these can be used to prepare plant pots, plastic woods, furniture etc.
High density polyethene is also known by the short form HDPE.
Whereas low density polyethene (LDPE), PVC, polystyrene and polypropylene are not safe plastics and they tend to harm the environment. So, they are not safe to store or preserve food items.
Thus, we can conclude that out of the given options HDPE polymers is used in plastic bottles and plastic containers.
Acids are sour in taste while Bases are bitter in taste . This is due to the pH that indicates acidity or basicity , and is defined as the hydrogen potential of a solution . ... Acids turn blue litmus paper into red whereas in case of Bases they turn red litmus paper into blue .
