Acid-Base Strength

The strength and weakness of an acid can be seen from the

amount of residual acid produced and how it tends to be
dissolved in water.

Strong Acids

Strong acids are acids that ionize

completely in water Examples of

2
strong acids include HCl, HBr, HI, H SO 4
etc. HCl when dissolved into water
forms hydrogen ions and chlorine
ions. Strong acids are strong

electrolytes that ionize completely in
water

Weak Acids

Weak acids are acids that are
only slightly ionized in water. For

example, acetic acid (CH COOH),

when CH COOH is dissolved in water

contains a mixture of molecules of
non-ionized acid, H O and conjugate
+

base.
