A) 294
B) 49
C) 298
D) 50
Correct Answer: B
Solution :
\[{{K}_{2}}C{{r}_{2}}{{O}_{7}}\,\,\to \,\,3{{H}_{2}}S{{O}_{4}}\,\,\to \,\,{{K}_{2}}S{{O}_{4}}\,\,+\,\,C{{r}_{2}}{{(S{{O}_{4}})}_{3}}\] \[+\,3\left( O \right)+3{{H}_{2}}\] No. of electrons lost \[=\,\,12-6=6\] \[\Rightarrow \ \ Equivalent\,\,weight\,\,=\,\,\frac{M}{6}=\frac{294}{6}=49\]You need to login to perform this action.
