What is the pH of a mol/dm solution of the strong monobasic acid HCl?
Answer and explanation
Correct answer: C. 4
- Step 1: For a strong monobasic acid mol/dm.
- Step 2: .
Answer
4.
Why not the others: 10: that is the pH of a base of the same concentration. -4: the sign of the logarithm is not reversed. 5: it adds 1 to the exponent.
