Strong Acid/Base Weak Acid/Base


Strong acid - ionise/dissociate completely producing H+ ion

Strong base - ionise/dissociate completely producing OH- ion

All are in ions state, No molecule left

Strong electrolyte with high conductivity  


Weak acid - ionise/dissociate partially producing H+ ion

Weak base - ionise/dissociate partially producing OH- ion

Most in undissociated molecule form

Poor electrolyte with low conductivity

HCl → H+ + Cl- CH3COOH ⇌ H+ + CH3COO-
