Either my online portal hates me, or I don't understand how to balance properly.
Balance reaction of arsenic(III) sulfide with nitric acid As2S3(s) + NO3-(aq) → H3AsO4(aq) + S(s) + NO(g)
Is this the correct balanced equation?
32 H2O + 24 As2S3(s) + 80 H+(aq) + 80 NO3-(aq) → 48 H3AsO4(aq) + 9 S8(s) + 80 NO(g)
If yes, which is the oxidizing reagent and what is the reducing reagent?
oxidn is loss of electrons.
It is reduced.
Reduction is gain of electrons. It is the oxidizing agent. Isn't that NO3^-?
The equation looks balanced to me; one never knows these days if S8 or S is required.
