Detailed explanation-1: -For instance, hydrochloric acid comes in at about pH 1.6, nitric acid at 1.08 and pure sulfuric acid at a whopping pH-12. That makes sulfuric acid the strongest ‘normal’ acid you’ll find. Anything more powerful is defined as a superacid.
Detailed explanation-2: -A pH less than 7 indicates an acidic solution while a pH of more than 7 indicates a basic solution. A pH close to 1 indicates a very strong acid while a pH just below 7 indicates the presence of a weak acid. Strong bases on the other hand have a pH close to 14 while weak bases have a pH just above 7.
Detailed explanation-3: -Hence, hydrochloric acid is a strong acid.
Detailed explanation-4: -Generally, a strong acid has a pH of about zero to 3. The stronger the acid, the better it dissociates in an aqueous solution, releasing more cationic hydrogen (H+) ions. Examples of strong acids include hydrochloric acid (HCl), hydrobromic acid (HBr), perchloric acid (HClO4), and sulfuric acid (H2SO4).
Detailed explanation-5: -Acid Rain and the pH Scale The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral-neither acidic or basic.
