What is the pH of 10⁻⁸ MHCl solution?
Options
- A8
- B7
- C< 7
- D8
Correct answer
C. < 7
Step-by-step solution
10⁻⁸ M indicates a very dilute solution. Thus, [ H ⁺ ] from water cannot be ignored. But dissociation of water is suppressed due to common ion effect. [ H ⁺ ] 10⁻⁷ , but less than 10⁻⁷ . Hence, pH of 10⁻⁸ M of HCl is less than 7 .
