The following are the differences between strong and weak acids:
|
STRONG ACID |
WEAK ACID |
|
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 |
