Calculate [ H ₃ O ⁺ ] of a monobasic acid if it is 0.04 % dissociated in 0.05 M solution.
Options
- A1 10⁻⁵
- B1.5 10⁻⁵
- C2.0 10⁻⁵
- D3.0 10⁻⁵
Correct answer
C. 2.0 10⁻⁵
Step-by-step solution
aligned & = Percentage dissociation 100 = 0.04 100 =4 10⁻⁴ & [ H ₃ O ⁺ ]= c =4 10⁻⁴ 0.05 M =2.0 10⁻⁵ aligned
