Question

С каккими из перечисленных веществ будет реагировать разбавленная серная кислота : гидрооксид калия , кислород , оксид цинка , оксид углерода , (4) , хлорид бария гидрооксид железа (3) . Напишите уровнение осуществимых реакций .

Answer 1

с гидроксидом калия , оксидом цинка,хлорид бария, гидроксидом железа, 

первая реакция нейтрализации: серная кислота+гидрооксид калия=сульфат калия(2)+вода

  серная кислота+оксид цинка=сульфат цинка+вода

 серная кислота+хлорид бария=сульфат бария+соляная кислота

так же   реакция нейтрализации получается соль(сульфат железа(3))+вода

Reactions of Dilute Sulfuric Acid with Listed Substances

Dilute sulfuric acid can react with various substances. Let's explore the reactions with the listed substances:

1. Hydroxide of Potassium (Potassium Hydroxide): - Dilute sulfuric acid will react with potassium hydroxide to form potassium sulfate and water. - The balanced chemical equation for this reaction is: ``` H2SO4 + 2KOH → K2SO4 + 2H2O ```

2. Oxygen: - Dilute sulfuric acid does not react with oxygen under normal conditions.

3. Zinc Oxide: - Dilute sulfuric acid will react with zinc oxide to form zinc sulfate and water. - The balanced chemical equation for this reaction is: ``` H2SO4 + ZnO → ZnSO4 + H2O ```

4. Carbon Oxide (Carbon Dioxide): - Dilute sulfuric acid does not react with carbon oxide under normal conditions.

5. Barium Chloride: - Dilute sulfuric acid will react with barium chloride to form barium sulfate and hydrochloric acid. - The balanced chemical equation for this reaction is: ``` H2SO4 + BaCl2 → BaSO4 + 2HCl ```

6. Iron(III) Hydroxide: - Dilute sulfuric acid will react with iron(III) hydroxide to form iron(III) sulfate and water. - The balanced chemical equation for this reaction is: ``` H2SO4 + 2Fe(OH)3 → Fe2(SO4)3 + 6H2O ```

Conclusion

Dilute sulfuric acid can react with potassium hydroxide, zinc oxide, barium chloride, and iron(III) hydroxide to form various products as indicated by the balanced chemical equations provided.
