In the following

NO3−+As2 S3+H2O→AsO43−+NO+SO42−+H+\mathrm{NO}_3^{-}+\mathrm{As}_2 \mathrm{~S}_3+\mathrm{H}_2 \mathrm{O} \rightarrow \mathrm{AsO}_4^{3-}+\mathrm{NO}+\mathrm{SO}_4^{2-}+\mathrm{H}^{+}

Equivalent weight of As2S3A s_2 S_3 (Molecular weight M) is
View answer and explanation
Correct option: D
M28\frac{M}{28}
Option D (M28\frac{M}{28}) is correct because the equivalent weight is the molecular weight divided by the total number of electrons transferred in the redox reaction.
