5mol of F e _ 2 ( C _ 2 O _ 4 ) _ 3 is oxidised by x mol of K _ 2 C...

5mol\text{5}\text{mol} of Fe2(C2O4)3F{e}_{2} ( {C}_{2}{O}_{4}{)}_{3} is oxidised by x\text{x} mol of K2Cr2O7{K}_{2}C{r}_{2}{O}_{7} in acidic medium, calculate the value of X\text{X} ?

Correct answer

5

Step-by-step solution

Eq of Fe2(C2O4)3F{e}_{2} ( {C}_{2}{O}_{4}{)}_{3} = eq of K2Cr2O7{K}_{2}C{r}_{2}{O}_{7}

5×6=mol×65 \times 6 = mol \times 6

Mol of K2Cr2O7{K}_{2}C{r}_{2}{O}_{7} = 5
