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: -So, the pH of 0.1M HCl is +1 which is quite less than 7 which indicates that HCl is a strong acid.
Detailed explanation-3: -The hydronium ion H3O+ is the strongest acid that can exist in aqueous solution because stronger acids dissociate by transferring a proton to water.
Detailed explanation-4: -pH 1 represents strong acid, getting progressively weaker as the pH rises. pH 7 is the neutral value of pure water at 25ºC and 1 atmosphere pressure.
Detailed explanation-5: -A strong acid, such as hydrochloric acid, at concentration 1 mol dm−3 has a pH of 0, while a strong alkali like sodium hydroxide, at the same concentration, has a pH of 14. Since pH is a logarithmic scale, a difference of one in pH is equivalent to a tenfold difference in hydrogen ion concentration.
