What Does Calcium Chloride and Sodium Bicarbonate Make?

When calcium chloride (CaCl₂) and sodium bicarbonate (NaHCO₃) are mixed together, they undergo a chemical reaction. The reaction produces calcium carbonate (CaCO₃), sodium chloride (NaCl), water (H₂O), and carbon dioxide (CO₂).

The balanced chemical equation for this reaction is:

CaCl₂ + 2NaHCO₃ → CaCO₃ + 2NaCl + H₂O + CO₂

Here’s a breakdown of what happens during the reaction:

• Calcium Chloride (CaCl₂): This is a salt that is highly soluble in water.
• Sodium Bicarbonate (NaHCO₃): Commonly known as baking soda, it is a weak base.
• Calcium Carbonate (CaCO₃): This is a white solid that is insoluble in water and is commonly found in rocks and shells.
• Sodium Chloride (NaCl): This is table salt, which is soluble in water.
• Water (H₂O): A byproduct of the reaction.
• Carbon Dioxide (CO₂): This gas is released during the reaction, which can be observed as bubbles.

This reaction is often used in educational settings to demonstrate chemical reactions and the formation of precipitates and gases.
