A strong acid is an acid that dissociates completely when in aqueous solution. A weak acid is an acid that does not dissociate completely when in aqueous solution. Example of strong acid: HCl(aq)...
The pK-values determine the difference between strong and weak acids in water: Strong acid have pKa,strong < 0.0 (so negative values!) H3O+ is the 'shifting' value of pKa = 0.0 Weak acids have by...
A strong acid dissociates more readily than a weak acid. So if you have a strong acid like HCl and you're writing the net ionic, you don't have to write HCl, but just write H+ because the H+ is...
