*and
*Ethanol + H2O2 + K2Cr2O7
To determine the oxidation equation, reduction equation, and overall equation for each of the given reactions, we need to identify the oxidizing and reducing agents involved.
1. H2O2 + H2SO4 + KMnO4:
Oxidizing agent: KMnO4
Reducing agent: H2O2 + H2SO4
To write the equations, we need to balance the atoms and charges in each equation:
Oxidation equation: H2O2 → O2
Reduction equation: Mn(VII) → Mn(II) + 4H2O
Overall equation: H2O2 + 2H2SO4 + KMnO4 → O2 + MnSO4 + K2SO4 + 4H2O
2. H2O2 + KMnO4:
Oxidizing agent: KMnO4
Reducing agent: H2O2
Balancing the atoms and charges in each equation:
Oxidation equation: H2O2 → O2
Reduction equation: Mn(VII) → Mn(II)
Overall equation: H2O2 + KMnO4 → O2 + MnO2 + KOH
3. Ethanol + H2O2 + K2Cr2O7:
Oxidizing agent: K2Cr2O7
Reducing agent: Ethanol + H2O2
Balancing the atoms and charges:
Oxidation equation: CH3CH2OH → CH3COOH
Reduction equation: Cr(VI) → Cr(III)
Overall equation: CH3CH2OH + H2O2 + K2Cr2O7 → CH3COOH + Cr2O3 + KOH + H2O
