Reaction between Sodium Bicarbonate and Calcium Hydroxide

When Sodium Bicarbonate (NaHCO3) reacts with Calcium Hydroxide (Ca(OH)2), a double displacement reaction takes place, resulting in the formation of two new compounds - Calcium Carbonate (CaCO3) and Water (H2O).

Chemical Equation

The chemical equation for the reaction between Sodium Bicarbonate and Calcium Hydroxide is:

NaHCO3 + Ca(OH)2 → CaCO3 + H2O + NaOH

Explanation of the Reaction

The reaction between Sodium Bicarbonate and Calcium Hydroxide is an acid-base reaction, where Sodium Bicarbonate acts as an acid and Calcium Hydroxide acts as a base.

When Sodium Bicarbonate is added to Calcium Hydroxide, the bicarbonate ion (HCO3-) reacts with the hydroxide ion (OH-) to form water and carbonate ion (CO32-). This is an acid-base reaction.

NaHCO3 + OH- → Na+ + H2O + CO32-

The resulting carbonate ion then reacts with the Calcium ion (Ca2+) in Calcium Hydroxide to produce Calcium Carbonate, which is an insoluble precipitate.

Ca2+ + CO32- → CaCO3

The Sodium ion (Na+) that is produced during the reaction remains in solution as Sodium Hydroxide (NaOH).

Na+ + OH- → NaOH

Conclusion

In summary, the reaction between Sodium Bicarbonate and Calcium Hydroxide results in the formation of Calcium Carbonate, Water, and Sodium Hydroxide. This reaction is an acid-base reaction, where Sodium Bicarbonate acts as an acid and Calcium Hydroxide acts as a base. Calcium Carbonate is an insoluble precipitate and can be used in various applications, such as in the production of cement and as a dietary supplement.
