A) \[\text{CrO}_{4}^{2-}\]
B) \[\text{C}{{\text{r}}_{\text{2}}}{{\text{(S}{{\text{O}}_{\text{3}}}\text{)}}_{\text{3}}}\]
C) \[\text{CrS}{{\text{O}}_{4}}\]
D) \[\text{C}{{\text{r}}_{\text{2}}}{{\text{(S}{{\text{O}}_{4}})}_{3}}\]
Correct Answer: D
Solution :
\[{{K}_{2}}C{{r}_{2}}{{O}_{7}}+3N{{a}_{2}}S{{O}_{3}}+4{{H}_{2}}S{{O}_{4}}\xrightarrow[{}]{{}}3N{{a}_{2}}S{{O}_{4}}\] \[+{{K}_{2}}S{{O}_{4}}+C{{r}_{2}}{{(S{{O}_{4}})}_{3}}+4{{H}_{2}}O\]You need to login to perform this action.
