At 27^ C . the degree of dissociation of HA (weak acid) in 0.5 M of its solution is 1 % . The concentrations of H ₃ O ⁻ , A ⁻ and HA at equilibrium (in mol L ⁻¹ ) are respectively
Options
- A0.005,0.005,0.495
- B0.05,0.05,0.45
- C0.01,0.01,0.49
- D0.005,0.495,0.005
Correct answer
A. 0.005,0.005,0.495
Step-by-step solution
aligned & [ H ⁺ ]= c & =0.5 (10⁻² ) & =0.005 & [ H ₃ O ]⁺=0.005 & [ ~A ⁻ ]=0.005 & [ HA ]=0.5- x & =0.5-0.005 & =0.495 aligned
