Question

Define strong acid and weak acids with examples?


Solution

Strong Acids - HCl (Hydrochloric acid), H2SO4 (Sulphuric acid)

Weak acids - H2CO3 (Carbonic acid), H2SO3 (Sulphurous acid)

strong acid is any acid that ionizes completely in solutions. This means it gives off the greatest number of hydrogen ions or protons when placed in a solution.

weak acid is an acid that dissociates incompletely, releasing only some of its hydrogen atoms into the solution. Thus, it is less capable than a strong acid at donating protons. These acids have higher pKa than strong acids, which release all of their hydrogen atoms when dissolved in water.
