Cr2O3 + 3Ca → 2Cr + 3CaO
The following reaction shows that nature of calcium?
Oxidising nature
reducing nature
Redox nature
None of these
The metal oxide is reduced to a metal i.e., from '+3' oxidation state to '0'oxidation state.
Hence this reaction shows the reducing nature of calcium.
A solution of CuSO4 is
The reaction of H2S + H2O2 → S + 2H2O manifests
