Identify the correct statement (s) in reflection to the following reaction :
`Zn+2HClrarr ZnCl_2+H_2`

Options

A. Zinc is acting as an oxidant
B. Chlorine is acting as a reluctant
C. Hydrogen ion is acting as an oxidant
D. Zinc is acting as a reluctant

Explanation

Writing the O.N of each element above its symbols we have
`Zn+2HCIrarr Zn CI_(2)+H_(2)`
(a) The O.N of Zn increases form 0 in Zn to +2 in `Zn CI_(2)` therefore Zn acts as a reductant thus option
(c ) is not correct
(b) The O.N of CI does not change therfore it neither acts as a reductant nor an oxidant therefore option (b) is not correct
(c ) The O.N of H decreae from +1 in `H^(+)` to 0 in `H_(2)` therefore `H^(+)` acts an oxidant thus option (c ) is correct (d) As explained in option (a) Zn acts as a reductant therefore it cannot act as an oxidant Thus option (c ) and (d) are correct
