For the coagulation of 10 mL of `Fe(OH)_3` sol, 2 mL of 1 MKBr is required. What is the coagulating value of KBr?

A

100

B

150

C

200

D

250

Text Solution

Verified by Experts

The correct Answer is:
C
2 mL of M KB r contains KBr=`(1)/(1000)xx2` mol =2 mol
`therefore` i.e., 1000 mL, of the sol requires KBr for complete coagulation=200 mol Hence, flocculation value of KBr=200
