Question

Alcohol content in a drunkard person can be determined by $K_{2}C{r}_2{O}_7$.

If true enter 1, else enter 0.

Answer 1

As a drunkard person takes a breath, alcohol content is oxidised to $C{H}_{3}CHO$ by $K_{2}C{r}_2{O}_7/H^{+}$ which in turn is reduced to $C{r}^{3+}$ (green).

Formation of green colour indicates alcohol content.

Therefore, the correct answer is 1.
