Respuesta :
The answer to this is saturation. When a solvent cannot dissolve any more solute, the substance has reached saturation and is saturated. However, there is also supersaturation when a solute can be dissolved in a solvent beyond saturation by altering the heat and physically changing the solution, then later reversing it.
Explanation:
A saturate is a solution which contains maximum amount of solute. So, when we further add solute into the solvent then solute is not able to dissolve in it and remains in its powdered or original form.
And, this point is known as saturation point and the solution is known as saturated solution.
A saturated solution is also able to conduct electricity.
Thus, we can conclude that in the given picture when no more cocoa can be dissolved. The solution has reached to its saturation point.
