Question

Megan prepares a pitcher of lemonade by adding a quarter cup of granular sugar to the mixture. Which action should she take so the sugar dissolves in the lemonade faster? A. Increase the amount of sugar. B. Add a small amount of powdered sugar. C. Stir the water continuously. D. Cool the pitcher. E. Reduce the original quantity of water.

Answer 1

Stir the water continuously, this is the only logical answer. Adding powdered sugar, decreasing the volume, increasing the amount of suga, cooling, all don't make the sugar dissolve quicker.

Answer 2

Answer: Option (C) is the correct answer.

Step-by-step explanation:

According to collision theory, more is the number of collisions between solute and solvent particles more will be the rate of reaction, that is, more readily products will be obtained.

So, when we stir a pitcher of lemonade by adding a quarter cup of granular sugar to the mixture then more number of collisions will take place between sugar and solution particles.

As a result, sugar will readily dissolve into the solution.

Therefore, we can conclude that the action stir the water continuously should Megan take so that the sugar dissolves in the lemonade faster.
