Reactivity of Nitric Acid with Substances

Nitric acid (HNO3) can react with various substances. Let's explore how it reacts with the given substances:

1. Copper (Cu): - Nitric acid reacts with copper to produce nitrogen dioxide gas, water, and copper(II) nitrate. - The reaction can be represented as: ``` 3Cu + 8HNO3 → 3Cu(NO3)2 + 2NO2 + 4H2O ``` Source: 2. Copper(II) oxide (CuO): - Nitric acid reacts with copper(II) oxide to form copper(II) nitrate, water, and nitrogen dioxide gas. - The balanced chemical equation for the reaction is: ``` 3CuO + 6HNO3 → 3Cu(NO3)2 + 3H2O + 3NO2 ``` Source: 3. Iron(II) hydroxide (Fe(OH)2): - Nitric acid reacts with iron(II) hydroxide to form iron(II) nitrate and water. - The balanced chemical equation for the reaction is: ``` Fe(OH)2 + 2HNO3 → Fe(NO3)2 + 2H2O ``` Source: 4. Sodium sulfate (Na2SO4): - Nitric acid reacts with sodium sulfate to form sodium nitrate, sulfuric acid, and water. - The balanced chemical equation for the reaction is: ``` 2Na2SO4 + 4HNO3 → 4NaNO3 + 2H2SO4 + O2 ``` Source: 5. Sulfur dioxide (SO2): - Nitric acid reacts with sulfur dioxide to form nitrogen dioxide, water, and sulfuric acid. - The balanced chemical equation for the reaction is: ``` 2HNO3 + 2SO2 → 2NO2 + 2H2O + 2H2SO4 ``` Source: 6. Carbon (C): - Nitric acid reacts with carbon to form carbon dioxide, nitrogen dioxide, and water. - The balanced chemical equation for the reaction is: ``` 4HNO3 + 6C → 4CO2 + 2N2 + 6H2O ``` Source: 7. Hydrogen (H2): - Nitric acid reacts with hydrogen to form nitrogen dioxide and water. - The balanced chemical equation for the reaction is: ``` 4HNO3 + 3H2 → 4NO2 + 3H2O ``` Source: 8. Iron(III) oxide (Fe2O3): - Nitric acid reacts with iron(III) oxide to form iron(III) nitrate and water. - The balanced chemical equation for the reaction is: ``` Fe2O3 + 6HNO3 → 2Fe(NO3)3 + 3H2O ``` Source: 9. Sodium hydroxide (NaOH): - Nitric acid reacts with sodium hydroxide to form sodium nitrate and water. - The balanced chemical equation for the reaction is: ``` HNO3 + NaOH → NaNO3 + H2O ``` Source: 10. Calcium carbonate (CaCO3): - Nitric acid reacts with calcium carbonate to form calcium nitrate, carbon dioxide, and water. - The balanced chemical equation for the reaction is: ``` CaCO3 + 2HNO3 → Ca(NO3)2 + CO2 + H2O ``` Source: These reactions demonstrate the diverse reactivity of nitric acid with various substances, resulting in the formation of different products.
