Hi there,
I have some trouble understanding redox reactions. Here is the question:
Sulphuric acid is one of the strongest inorganic acides which in some reaction shows oxidation properties. In which of reactions below, sulphuric acid acts as oxidating tool?
A.[tex]
\text{H}_2{SO}_4 + \text{CaCO}_3 \rightarrow \text{CaSO}_4 + \text{CO}_2 + \text{H}_2{O}
[/tex]
B.[tex]
2 \text{H}_2{SO}_4 + \text{Cu} \rightarrow \text{CuSO}_4 + \text{SO}_2 + 2 \text{H}_2{O}
[/tex]
C.[tex]
\text{H}_2{SO}_4 + \text{BaCO}_3 \rightarrow \text{BaSO}_4 + \text{CO}_2 + \text{H}_2{O}
[/tex]
D.[tex]
\text{H}_2{SO}_4 + \text{Ca(OH)}_2 \rightarrow \text{CaSO}_4 + 2 \text{H}_2{O}
[/tex]
Thank you.
