Observe the following solutions (i) 1 ~L of 10⁻⁶ M Ag NO ₃ (ii) 1 ~L of 10⁻⁷ M AgNO ₃ (iii) 1 ~L of 10⁻⁹ M Ag NO ₃ (iv) 1 ~L of 10⁻³ M AgNO ₃ (v) 1 ~L of 10⁻⁵ M NaCl Which of the above two solutions when mixed will give a white precipitate, AgCl ? ( . Given K _ sp of AgCl =1 10⁻¹⁰ )

Step-by-step solution

A solution that has the concentration of Ag ⁺ or Cl ⁻ greater than or equal to the solubility of Ag ⁺ or Cl ⁻ from the value of K_ s p , will precipitate out. aligned & K _ sp = [ Ag ⁺ ] [ Cl ⁻ ]=( s )( s )= s ^2=1 10⁻¹⁰ M ^2 & s =10⁻⁵ M aligned Thus, (iv) 1 ~L of 10⁻³ M AgNO ₃ and (v) 1 ~L of 10⁻⁵ M NaCl will precipitate
