The coagulation of 200 ml of a positive colloid took place when 0.73g HCI was added to it. The floculation value of HCI for the colloid is :

A

150

B

200

C

100

D

36.5

Text Solution

Verified by Experts

The correct Answer is:
C
number of moles of hci added `=(0.73)/(36.5)=0.02mol =20m" "mol`
Then number of millimoles required by 1000ml sol `=(20)/(200)xx100m mol`.
