Most Important Selected Qs for JEE AdvancedChemistryIonic Equilibrium
To 1 L solution, which is 0.1 M in AgNO ₃ and 0.2 M in CuSO ₄ , a 1 L 0.4 M NaCl solution is added. If the final concentration of Cu ⁺ in the solution is x 10^ -y (x . and y are natural numbers) then (x+y) is. ( K_ s p .( AgCl )=1.6 10⁻¹⁰, ~K _ sp ( CuCl )=10⁻⁶ )
Correct answer
6
Step-by-step solution
array ll & Ag ⁺+ Cl ⁻ AgCl ; K =1.6 10⁻¹⁰ t =0 & 0.1 0.4 & 0 0.3 & Cu ⁺+ Cl ⁻ CuCl K =10^6 t =0 & 0.1 0.3 & 0 0.2 mole & [ Cl ⁻ ]= 0.2 2 =0.1 M array CuCl ( s ) , is at equilibrium after precipitation stopes so [ Cu ⁺ ] [ Cl ⁻ ]=10⁻⁶ [ Cu ⁺ ]= 10⁻⁶ 0.1 =10⁻⁵=1 10⁻⁵ x+y=6
