Dissociation constant and degree of dissociation of weak acid are 1.8 10⁻⁵ and 0.03 respectively. What will be the concentration of solution of weak acid?
Options
- A0.2 M
- B0.02 M
- C0.5 M
- D0.05 M
Correct answer
B. 0.02 M
Step-by-step solution
aligned & K _ a = ^2 c & c = K _ a ^2 = 1.8 10⁻⁵ (0.03)^2 = 1.8 10⁻⁵ 9 10⁻⁴ =0.02 M aligned
