Calculate the pH of 1.36 10⁻² M solution of perchloric acid.
Options
- A1.43
- B1.86
- C2.43
- D2.86
Correct answer
B. 1.86
Step-by-step solution
Perchloric acid is a strong monobasic acid. Hence, [ H ₃ O ⁺ ]=1.36 10⁻² M aligned pH & =- ₁₀ [ H ₃ O ⁺ ] & =- ₁₀ [1.36 10⁻² ] & =- ₁₀ 1.36- ₁₀ 10⁻² & =- ₁₀ 1.36+2 & =2-0.1335 pH & =1.86 aligned
