Which of the following electrolytes will have maximum coagulating value for A g I A g + sol?

Options

  1. AN a 2 S
  2. BN a 3 P O 4
  3. CN a 2 S O 4
  4. DNaCl

Correct answer

D. NaCl

Step-by-step solution

Coagulating power ∝ 1 c o a g u l a t i n g value ∝ charge As A g I A g + is a positive sol so negative ion will cause the coagulation. Ions of the given electrolytes are, S 2 - , P O 4 3 - , S O 4 2 - and C l - . As C l - has minimum charge thus has maximum coagulating value.
