Which best describes solubility?
a
the speed at which a substance dissolves
b
the temperature at which subtances become a mixture
c
the amount of surface area per a given mass
d
the ability of one substance to dissolve in another
d
the ability of one substance to dissolve in another
d
the ability of one substance to dissolve in another
The correct answer is option d: the ability of one substance to dissolve in another.
Solubility refers to the ability of a substance, known as the solute, to dissolve in another substance, known as the solvent, to form a homogenous mixture called a solution.
To determine the solubility of a solute in a solvent, several factors need to be considered, including temperature and pressure. The concentration of the solute in the solvent can also affect solubility.
Option a, the speed at which a substance dissolves, is related to the rate of dissolution, which can be influenced by factors such as temperature, surface area, and stirring.
Option b, the temperature at which substances become a mixture, does not accurately describe solubility. Although temperature can affect solubility, it is not the defining characteristic.
Option c, the amount of surface area per a given mass, describes the concept of surface area-to-volume ratio, which can impact the rate of dissolution but is not directly related to solubility.
Overall, option d provides the most accurate description of solubility, emphasizing the ability of one substance to dissolve in another.
