Question
Which of the following usually makes a substance dissolve faster in a solvent?Group of answer choiceslowering the temperatureagitating the solutiondecreasing the number of particlesincreasing the particle size of the solute
Solution
Agitating the solution usually makes a substance dissolve faster in a solvent.
Here's why:
-
When you agitate a solution, you're essentially stirring it. This movement helps distribute the solute particles throughout the solvent.
-
This distribution increases the contact between the solute and solvent particles, which increases the rate of dissolution.
-
Agitation also helps to disperse clumped particles. When particles are clumped together, only the particles on the surface are exposed to the solvent. By breaking these clumps apart, more particles are exposed, which again increases the rate of dissolution.
So, out of the options provided, agitating the solution is the one that usually makes a substance dissolve faster in a solvent.
