Detailed Solution

The pH scale, which ranges from 1 to 7, is used to determine acid pH. Moving down the scale from 7 to 1 increases the acid's strength. On the pH scale, high acidity is a 1 and neutrality is a 7. Because HCl is strongly acidic, its pH is less than 7, whereas basicity increases from 7 to 14 on this scale. As a result, all acids have a pH of less than 7.
