The vanadium salt, $\text{VOSO}_4$, dissolves in water and is very reactive with powdered manganese in dilute sulfuric acid. The reaction equation is given below. $\text{Mn}(s) + 2\text{VOSO}_4(aq) + 2\text{H}_2\text{SO}_4(aq) \rightarrow \text{V}_2(\text{SO}_4)_3(aq) + \text{MnSO}_4(aq) + 2\text{H}_2\text{O}(l)$ Which statement correctly describes this reaction?
- AHydrogen is oxidised in the reaction.
- BManganese is the reducing agent in this reaction.
- CSulfuric acid is the oxidising agent in this reaction.
- DThe oxidation state of the vanadium changes from $+5$ to $+3$.
