The correct Answer is:
To determine the classification of hydrogen peroxide (H₂O₂), we will analyze its structure and the number of replaceable hydrogen atoms it contains. ### Step-by-Step Solution: 1. **Understanding the Structure of H₂O₂**: - Hydrogen peroxide has the chemical formula H₂O₂, which indicates that it contains two hydrogen (H) atoms and two oxygen (O) atoms. 2. **Identifying Replaceable Hydrogen Atoms**: - In acids, the classification into monobasic, dibasic, and tribasic depends on the number of replaceable hydrogen ions (H⁺). - A monobasic acid has one replaceable hydrogen atom, a dibasic acid has two, and a tribasic acid has three. 3. **Analyzing H₂O₂**: - When H₂O₂ dissociates, it can release two hydrogen ions (H⁺). - The first dissociation can be represented as: \[ H₂O₂ \rightarrow H⁺ + HO₂⁻ \] - The second dissociation can be represented as: \[ HO₂⁻ \rightarrow H⁺ + O₂^{2-} \] - This shows that both hydrogen atoms in H₂O₂ can be replaced, indicating that there are two replaceable hydrogen ions. 4. **Conclusion**: - Since H₂O₂ can release two hydrogen ions, it is classified as a dibasic acid. ### Final Answer: H₂O₂ is a dibasic acid.
