Answer 2

Reaction of Sodium Hydroxide with Various Substances

When sodium hydroxide (NaOH) reacts with different substances, various chemical reactions occur. Let's explore the reactions with the substances you've mentioned.

1. CO2 (Carbon Dioxide): When sodium hydroxide reacts with carbon dioxide, it forms sodium carbonate and water. The balanced chemical equation for this reaction is: ``` 2NaOH + CO2 → Na2CO3 + H2O ``` Source: 2. Ca(OH)2 (Calcium Hydroxide): The reaction between sodium hydroxide and calcium hydroxide results in the formation of calcium carbonate and water. The balanced chemical equation for this reaction is: ``` Ca(OH)2 + CO2 → CaCO3 + H2O ``` Source:

3. FeO (Iron(II) Oxide): Sodium hydroxide does not react directly with iron(II) oxide in a simple acid-base reaction. However, it can react with iron(II) oxide in more complex reactions under specific conditions, but the direct reaction is not a common one.

4. KNO3 (Potassium Nitrate): Sodium hydroxide does not directly react with potassium nitrate in a simple acid-base reaction. The reaction between sodium hydroxide and potassium nitrate would involve more complex processes and is not a typical reaction.

In summary, sodium hydroxide reacts with carbon dioxide and calcium hydroxide to form sodium carbonate and calcium carbonate, respectively, along with water. However, it does not undergo simple acid-base reactions with iron(II) oxide and potassium nitrate.
