The following are the differences between strong and weak acids:




Most molecules of strong acid split into ions water and produce large amounts of hydrogen ions.

Only a few molecules split into ions in water and thus produce less amount of hydrogen ions.

Since the number of ions are more, they are better conductors of electricity

Since the number of ions are less, they are weak conductors of electricity

pH value is very low between 0-3

pH value is roughly between 3-5

These cause more corrosion

These cause less corrosion

These react violently with metals to give more vigorous fizzing.

These react less violently with metals to give less rigorous fizzing.

These are usually mineral acids such as HCl, H 2 SO 4

These are usually natural acids such as Citric acid, Acetic acid
