Explain how the properties of the reactants (acidic vinegar and basic baking soda) influence the reaction. Highlight the role of the periodic table in predicting the behavior of these substances, particularly the reactivity of the sodium ion (Na⁺) and the bicarbonate ion(HCO₃⁻). (Use at least 2 full sentences with good spelling and grammar in your answer.)

Answer 1

The properties of acidic vinegar, which contains acetic acid (CH₃COOH), and basic baking soda, which is sodium bicarbonate (NaHCO₃), play a crucial role in their reaction. When mixed, the hydrogen ions from the acetic acid react with the bicarbonate ions (HCO₃⁻) from the baking soda, producing carbon dioxide gas, water, and sodium acetate; this effervescent reaction can be predicted by examining the positions of the elements on the periodic table.

The reactivity of the sodium ion (Na⁺) and the bicarbonate ion (HCO₃⁻) can be understood through their placement in the periodic table: sodium, a highly reactive alkali metal, readily forms ionic compounds, while bicarbonate, derived from the carbonate family, displays amphoteric properties, allowing it to engage in both acidic and basic reactions. This behavior is indicative of the underlying trends in reactivity and charge interactions that the periodic table helps to highlight.
