Calcium hydroxide, Ca(OH)2 is a base and neutralizes acid.
When a solution is acidic it contains excess hydrogen (H+) ions, calcium produces the hydroxide ion (OH-) in water, which reacts wit h the H+ ions to produce water.
OH- + H+ --> H2O
the milk of lime is... wait for this... the lime of milk. ================================================================== Kidding aside from the first answer, milk of lime is another common name for limewater, a saturated solution of calcium hydroxide. It got its name from the process of its preparation, wherein excess calcium hydroxide is stirred in pure water and filtering off the excess insoluble Ca(OH)2. When excess calcium hydroxide is added to limewater, a suspension of calcium hydroxide particles remains, giving it a milky aspect, in which case it has the common name of milk of lime.
One mole of calcium phosphide on reaction with excess water produces calcium hydroxide and phosphine gas. This reaction can be represented as Ca3P2 + 6H2O → 3Ca(OH)2 + 2PH3.
Antacid tablets work by neutralizing excess acid in the stomach, which helps provide relief from conditions like indigestion, heartburn, and acid reflux. They contain ingredients such as calcium carbonate or magnesium hydroxide that react with the acid to produce salt and water, thereby reducing acidity in the stomach.
Calcium carbonate in Rennie tablets works as an antacid by neutralizing excess stomach acid to provide relief from indigestion, heartburn, and upset stomach. It helps to soothe irritation in the stomach lining and reduce symptoms of acidity.
Antacids work by neutralizing excess stomach acid, which helps to relieve symptoms of indigestion and heartburn. They typically contain ingredients such as calcium carbonate, magnesium hydroxide, or aluminum hydroxide that react with the acid to form neutral substances like water and salt. This neutralization process raises the pH in the stomach, reducing acidity and providing relief from discomfort.

Calcium hydroxide (Ca(OH)₂) precipitates do not dissolve in excess sodium hydroxide (NaOH) because calcium hydroxide is only slightly soluble in water and its solubility does not significantly increase in a strongly basic environment. While NaOH increases the concentration of hydroxide ions (OH⁻), it does not provide a mechanism for dissolving the already formed Ca(OH)₂ precipitate. Instead, the presence of excess hydroxide ions can actually promote the formation of more stable complexes, such as calcium hydroxide remaining in its solid form. Thus, the equilibrium favors the solid phase rather than dissolution.

SINCE CARBONATE & HYDROXIDE'S ARE NEGATIVE ELEMENTS(eg..OH-) WHEN USED WITH ACIDIC (pH<7)ENVIRONMENT (i.e..POSITIVE ELEMENTS( H+))FORMS A NEUTRAL COMPOUND.HENCE USED FOR NEUTRALIZATION.
When excess calcium hydroxide is added to limewater, a suspension of calcium hydroxide particles remains, giving it a milky aspect, in which case it has the common name of milk of lime. Milk of lime is an alkaline solution with a pH of 12.3.
in stomach food is treated with acid for further breakdown by enzymes which work in acidic medium. Sometimes stomach produces extra acid than needed. Antacids as the name suggests are taken in the body to neutralise that excess acid generated in the stomach and thus relieve the patient of the pain caused by it.
Most medications include antacids, which are weak bases (e.g. calcium carbonate, aluminum hydroxide, magnesium hydroxide) to neutralize excess stomach acid.

The balanced net ionic equation for when a suspension of copper (II) hydroxide is treated with excess ammonia water is: Cu(OH)2(s) + 4NH3(aq) ⟶ [Cu(NH3)4]2+(aq) + 2OH-(aq)
