Acids and Bases as Products

Postby HannahLewis » Wed Jul 27, 2016 5:03 am

Could someone explain to me how when an acid and base react they produce water and salt?

Let's take an example of a strong base and acid reacting:

HCl + NaOH --> NaCl + H2O

The lone pair on the oxygen will attack the H on the H-Cl, and the H-Cl bond will break. The Na+ cation and the Cl- anion will then interact, forming a neutral salt.

If a strong acid and strong base react, the salt will be neutral.
If a strong acid (HBr) and weak base (NH3) react, the resulting salt will be slightly more acidic (pH<7)
If a weak acid (HF) and a strong base (KOH) react, the resulting salt KF will be slightly more basic (pH>7)
