Show Answer

Answer:

Correct Answer: 12. (d)

Solution:

  1. $n$-factor of dichromate is 6 .

Also, $n$-factor of Mohr’s salt is 1 as :

$\because 1$ mole of dichromate $=6$ equivalent of dichromate.

$\therefore 6$ equivalent of Mohr’s salt would be required.

Since, $n$-factor of Mohr’s salt is 1,6 equivalent of it would also be equal to 6 moles.

Hence, 1 mole of dichromate will oxidise 6 moles of Mohr’s salt.
