Baking soda is mixed with water, and no bubbles are produced. When baking soda is mixed with vinegar, it bubbles and foams rapidly.
What chemical property of baking soda is shown in this scenario?
• flammability
• boiling point
• reactivity
• color change
The chemical property of baking soda shown in this scenario is reactivity.
The chemical property of baking soda shown in this scenario is reactivity. When mixed with vinegar, the baking soda undergoes a chemical reaction, resulting in the formation of bubbles and foam. This reaction is due to the release of carbon dioxide gas when the two substances are combined.
In this scenario, the chemical property of baking soda that is shown is reactivity. Reactivity refers to how a substance reacts when it comes into contact with another substance or undergoes a chemical change.
When baking soda (sodium bicarbonate) is mixed with water, no bubbles are produced because water does not react chemically with baking soda. However, when baking soda is mixed with vinegar (acetic acid), a reaction occurs resulting in the production of carbon dioxide gas. This reaction is represented by the following equation:
Sodium bicarbonate (baking soda) + Acetic acid (vinegar) → Carbon dioxide gas + Water
2NaHCO3 + CH3COOH → CO2 + H2O
The release of carbon dioxide gas causes the bubbling and foaming observed in the reaction. This reaction is an example of an acid-base reaction, where the bicarbonate ion in the baking soda reacts with the hydrogen ion from the acetic acid. This reaction is specific to baking soda and vinegar and demonstrates the reactivity of baking soda with acids. Therefore, the correct answer is "reactivity."
