A) 5
B) 50
C) 54
D) None of the above
Correct Answer: C
Solution :
Flocculation value is the amount of electrolyte, in millimoles required to bring about complete coagulation of 1 L of colloidal solution. Amount of AB in 5.4 mL of 0.2 M AB \[=\frac{5.4\times 0.2}{1000}=1.08\times {{10}^{-3}}mol\] \[20\text{ }mL\] of \[A{{s}_{2}}{{S}_{3}}\] requires AB for coagulation \[=1.08\times {{10}^{-3}}mol\] \[1000mL\] of As\[A{{s}_{2}}{{S}_{3}}\] requires AB (i.e., flocculation value) \[=\frac{1.08\times {{10}^{-3}}}{20}\times 1000\] \[=0.054\text{ }mol=54\]milfimolYou need to login to perform this action.
