Question

Which of these factors will cause a solid solute to dissolve faster?

increasing the air temperature

increasing the amount of solute

increasing the amount of solvent

increasing the surface area of solute

Answer 1

Answer: The factor that would most likely cause a solid solute to dissolve faster is increasing the surface area of the solute. The more exposed its particles are to the solvant, the easier it is to dissolve. Of course, many factors might interfere in dissolution, such as temperature, polarity and others, but having in mind the options given, the surface area would be the most effective.

Answer 2

The correct answer among the choices given is the last option. Increasing the surface area of the solute will increase the dissolution of a solute in the solvent. The dissolution rate is affected by a number of factors like temperature, pressure, particle size and the polarity.
