Define strong acid and weak acids with examples?
Strong Acids - HCl (Hydrochloric acid), H2SO4 (Sulphuric acid)
Weak acids - H2CO3 (Carbonic acid), H2SO3 (Sulphurous acid)
A 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.
A 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.
