Adding a base
In a saturated solution, the rate of dissolution and precipitation are in equilibrium. Therefore, when solute is added, the solution is already at the maximum capacity to hold the solute. This causes the additional solute to remain as solid, as it cannot dissolve further without increasing the temperature or changing the conditions.
The addition of a crystal to an aqueous solution can act as a seed for the precipitation of solute particles out of the solution through a process known as crystallization. This occurs when the crystal provides a surface onto which the solute particles can adhere and form a solid precipitate, causing them to come out of the solution.
As the saturated solution is cooled slowly, the solubility of the solute decreases due to the decrease in temperature. This causes the excess solute to start crystallizing out of the solution in the form of solid crystals. The crystals will continue to grow as more solute particles come out of solution until equilibrium is reached.
Yes, a salt-saturated solution can be used to melt ice because the presence of salt lowers the freezing point of water. This causes the ice to melt at a lower temperature than 0°C, making it an effective method for de-icing surfaces.

When a cooled saturated potassium nitrate solution is added to water, the solubility of potassium nitrate decreases due to the decrease in temperature. This causes the equilibrium to shift to the left, leading to the precipitation of excess potassium nitrate as solid crystals.
The destabilization of a colloidal solution is possible, for example, by adding salt.

The pH of a solution increases when the concentration of hydroxide ions (OH-) increases, making the solution more basic or alkaline. This can occur by adding a base or by removing hydrogen ions (H+) from the solution.
Adding a base will make the pH go up (increasing of OH- ions concentration).
The presence of hydrogen ions (H+) in a substance causes it to be acidic. In an aqueous solution, hydrogen ions are responsible for the characteristic sour taste and ability to react with bases.
When a saturated solution is heated, the solubility of the solute generally increases due to the temperature dependency of solubility. This results in the solution no longer being saturated and more solute being able to dissolve. For example, if you have a saturated sugar solution at room temperature and then heat it, more sugar molecules can dissolve in the solution because solubility of sugar increases with temperature, making it unsaturated.
