What are strong acids? Give examples ......!!!!!!
Answers
Answer:
· A strong acid is an acid that is completely dissociated or ionized in an aqueous solution. It is a chemical species with a high capacity to lose a proton, H+. In water, a strong acid loses one proton, which is captured by water to form the hydronium ion: HA(aq) + H2O → H3O+(aq) + A−(aq).
Answer:
A strong acid is an acid that is completely dissociated or ionized in an aqueous solution. It is a chemical species with a high capacity to lose a proton, H+. In water, a strong acid loses one proton, which is captured by water to form the hydronium ion:
HA(aq) + H2O → H3O+(aq) + A−(aq)
Diprotic and polyprotic acids may lose more than one proton, but the "strong acid" pKa value and reaction only refers to the loss of the first proton.
Strong acids have a small logarithmic constant (pKa) and a large acid dissociation constant (Ka).
Most strong acids are corrosive, but some of the superacids are not corrosive. In contrast, some of the weak acids (e.g., hydrofluoric acid) may be highly corrosive.
Note: As acid concentration increases, the ability to dissociate diminishes. Under normal conditions in water, strong acids dissociate completely, but extremely concentrated solutions do not.
Examples of Strong Acids
While there are many weak acids, there are few strong acids. The common strong acids include:
HCl (hydrochloric acid)
H2SO4 (sulfuric acid)
HNO3 (nitric acid)
HBr (hydrobromic acid)
HClO4 (perchloric acid)
HI (hydroiodic acid)
p-toluenesulfonic acid (an organic soluble strong acid)
methanesulfonic acid (a liquid organic strong acid)
