With respect to the following reaction, which is the correct statement? #2HNO_3(aq) + 3H_2S(aq) rarr 3S(s)+2NO(g) +4H_2O#; a. both sulfur and nitrogen are reduced; b. nitrogen is reduced and sulfur is oxidized; c. oxygen is oxidized; d. this is not redox.
Can you write the redox half equations?
Try to represent the sulfur oxidation.
This is (I take it) a first year chemistry problem? Surely it's at least A level?
