Vedclass · Answer

(A) The balanced chemical equation for the reaction between acidic $K_2Cr_2O_7$ and $H_2S$ is: $K_2Cr_2O_7 + 4H_2SO_4 + 3H_2S \longrightarrow K_2SO_4 + Cr_2(SO_4)_3 + 7H_2O + 3S$ In this redox reaction,the dichromate ion is reduced to chromium$(III)$ sulfate $(Cr_2(SO_4)_3)$,and $H_2S$ is oxidized to elemental sulfur $(S)$. $K_2SO_4$ is also formed as a byproduct. $CrSO_4$ (chromium$(II)$ sulfate) is not formed in this reaction.

Which of the following is not formed when $H_2S$ reacts with acidic $K_2Cr_2O_7$ solution?
