Bronsted - Lowry theory
This is the 'proton transfer' view of acid-base reactions as represented
by the ionisation of hydrogen chloride in aqueous solution.
A proton (the H ion) has been transferred from the acid (HCl) to the base
The acid HCl(aq) is a proton (H) donor.
The base H2O(l) is a proton (H) acceptor.
An acid-base reaction involves two conjugate acid-base pairs.
When the acid HCl(aq) donates a proton it forms its conjugate base:
When the base H2O(l) accepts a proton it forms its conjugate acid:
The conjugate pairs H3O/H2O and HCl/Cl show that the acid and base differ
1. H2SO4(aq) + KOH(aq) - KHSO4(aq) + H2O(l)
2. KHSO4(aq) + KOH(aq) - K2SO4(aq) + H2O(l)
