Which of the following defines the rate at which a solute dissolves into a solvent?
a. rate of dilution
b. rate of dissolution
c. solvent velocity
d. rate of refraction

The correct answer is B. Rate of dissolution

Explanation:

In chemistry, a dissolution occurs as a substance or liquid called solute dissolves or is mixed with other called solvent. Additionally, the rate of this process refers to the Rate of dissolution, this describes the degree at which both substances mix and the speed at which this occurs. Besides this, the rate of dissolution is affected by many factors that include the type of solute and solvent, the size of the particles dissolved, the temperature and the surface area. According to this, the rate at which a solute dissolves into a solvent is the Rate of dissolution.
