Question

The concentration of a solution is directly related to

• A. Solubility
• B. Temperature
• C. Pressure
• D. All of the above

Answer 1

The correct option is D

All of the above

All of the factors can affect the concentration of solutes dissolved in the solvent. Solubility is a characteristic of the solvent. Temperature and pressure have an effect on the concentration of the solution as well. For example, you can often dissolve more sugar in water at higher temperatures as the solubility increases. The space between the water molecules increases and more sugar molecules can fit in. Hence lowering the pressure can also affect the concentration.
