Question

in the reaction,so2+2h2s-----2h2o+3s
identify reducing agent
(1)so2
(2)h2s
(3)h2o
(4)s

Answer 1

In the reaction SO2 is reduced to S as oxygen is removed.
H2S is oxidised to S as hydrogen is removed.

The species getting oxidised facilitates the reduction process and is the reducing agent.

Hence, H2S is the reducing agent and Oxidising agent is SO2.

Answer 2

Answer:

The answer is$\mathrm{H}_{2} \mathrm{~S}$.

Explanation:

A reducing agent (also understood as a reductant, reducer, or electron donor) exists as a chemical species that "donates" an electron to an electron recipient (named the oxidizing agent, oxidant, oxidizer, or electron acceptor).

An oxidation-reduction (redox) reaction exists as a kind of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction exists any chemical reaction in which the oxidation number of a molecule, atom, or ion differences by gaining or losing an electron.

$\mathrm{SO}_{2}+\mathrm{H}_{2} \mathrm{~S} \rightarrow 2 \mathrm{H}_{2} \mathrm{O}+3 \mathrm{~S}$

+4           -2         0

Hence, The answer is$\mathrm{H}_{2} \mathrm{~S}$.
