There will be increase in solubility.
What means solubility in water?
- Water solubility is a measure of the amount of chemical substance that can dissolve in water at a specific temperature.
- The unit of solubility is generally in mg/L (milligrams per liter) or ppm (parts per million).
- Sugar cubes added to a cup of tea or coffee are a common example of a solution.
- The property which helps sugar molecules to dissolve is known as solubility.
- Hence, the term solubility can be defined as a property of a substance (solute) to dissolve in a given solvent.
