Approved Tutor Answer11 Months agoThe pH of a solution indicates its acidity or alkalinity. For hydrochloric acid (HCl), which is a strong acid, it completely dissociates in water. This means that a 0.1M solution of HCl will produce 0.1 moles of hydrogen ions (H+) per liter.
Calculating pH
The formula to calculate pH is:
pH = -log[H+]
Applying the Formula
For a 0.1M HCl solution:
- [H+] = 0.1M
- pH = -log(0.1)
Result
Calculating this gives:
pH = 1
Therefore, the pH of a 0.1M HCl solution is 1, indicating it is quite acidic.
