Answers to Your Common Questions
A water solution is a mixture in which a solute is dissolved in water, resulting in a homogeneous liquid. Examples include salt water, sugar water, and lemonade.
To make a water solution, you need to dissolve a solute in water. Start by adding a small amount of the solute to the water, and stir until it dissolves. Repeat until all of the solutes is dissolved.
Not all solutes dissolve in water. Some factors that affect solubility include the temperature, pressure, and polarity of the solute and solvent. Generally, polar solutes (those with a partial positive and negative charge) are more likely to dissolve in water than nonpolar solutes.
Some ways to increase solubility include heating the water (which increases the kinetic energy and allows more solute to dissolve), using a smaller particle size for the solute (which increases surface area and allows for more contact with the solvent), or using a different solvent with a higher solubility for the solute.
Concentration is typically measured in moles per liter (M). To calculate the concentration of a water solution, divide the moles of solute by the volume of solution in liters.
Yes, it is possible for a water solution to become oversaturated with solute. This occurs when the solution has reached its maximum solubility, and any additional solute will not dissolve. In some cases, oversaturation can result in the formation of crystals or precipitates.
