Question

Adding solute will change several properties of a pure substance. For example, a pure substance like water has a boiling point of 100ºC, but its boiling point is expected to increase when solute like salt will be added to it, changing now a property of water. This is the main reason why saltwater is not easy to evaporate compared to pure water when exposed to the heat of the sun. In life, if we interpret a solute as a lesson that definitely changes our perspective or ideals in life, what would that great lesson that leads you to change?

a) The importance of perseverance
b) The value of adaptability
c) The significance of empathy
d) The power of humility

Answer 1

Adding a solute to pure water changes its boiling and freezing points, a colligative property that can be seen in real-world applications like antifreeze in radiators.

Step-by-step explanation:

When a solute is added to pure water, several properties change, including the boiling and freezing points. This phenomenon is known as the colligative property of solutions. As an example, adding salt to water increases the boiling point because the ions in salt form attractions with water molecules, preventing them from easily transitioning to the gas phase during boiling. One practical application of adjusting the freezing and boiling points is the use of antifreeze in car radiators; it lowers the water's freezing point and allows the car to operate at temperatures above 100°C. The increase in boiling point with the concentration of nonvolatile solute particles is precisely quantifiable using an appropriate mathematical equation.
