A) 4 and 5
B) 4 and 8
C) 8 and 4
D) 8 and 9
Correct Answer: C
Solution :
\[C{{r}_{2}}O_{7}^{2-}+2O{{H}^{-}}\xrightarrow[{}]{{}}2CrO_{4}^{2-}+{{H}_{2}}O\]\[pH>7(x>7)\] \[2CrO_{4}^{2-}+2{{H}^{+}}\xrightarrow[{}]{{}}C{{r}_{2}}_{7}^{2-}+{{H}_{2}}O\]\[pH<7(y<7)\]You need to login to perform this action.
