What will happen to the pH of water when lime is added?

When lime, which is chemically known as calcium hydroxide, is added to water, it undergoes a dissociation process that supplies hydroxide ions (OH-) into the solution. The introduction of these hydroxide ions leads to an increase in the concentration of hydroxide in the water, resulting in a higher pH value. Typically, lime is used in water treatment processes to increase pH and reduce acidity, making the water less corrosive and more suitable for various applications. Therefore, the pH of the water will indeed increase upon the addition of lime.
