F e ( O H ) 3 can be separated from A l ( O H ) 3 by the addition of

Options

  1. ANaOH solution
  2. BNaCl solution
  3. CDil. HCl solution
  4. DN H 4 C l & N H 4 O H

Correct answer

D. N H 4 C l & N H 4 O H

Step-by-step solution

Due to common ion effect of N H 4 + , concentration of O H - decreases, as K s p F e ( O H ) 3 < K s p A l ( O H ) 3 thus F e ( O H ) 3 get precipitated first.
