What is the Difference Between Caro’s Acid and Marshall’s Acid?
🆚 Go to Comparative Table 🆚Caro's acid and Marshall's acid are inorganic acid compounds containing sulfate groups. The key difference between Caro's acid and Marshall's acid lies in the number of sulfate groups in each compound:
- Caro's Acid: This acid has the chemical formula H2SO5 and contains one sulfate group. Its oxidation state of sulfur is +6 due to the presence of two peroxy oxygens.
- Marshall's Acid: This acid has the chemical formula H2S2O8 and contains two sulfate groups. Similar to Caro's acid, its oxidation state of sulfur is +6 due to the presence of two peroxy oxygens.
Both Caro's acid and Marshall's acid are used as powerful oxidizing agents in various chemical reactions.
