2. Elektrolit Lemah
a. Asam lemah
HxZ(aq) ←→ x H+(aq) + Zx–(aq)
Contoh : CH3COOH(aq) ←→ H+(aq) + CH3COO–(aq)
H2SO3(aq) ←→ 2 H+(aq) + SO32–(aq)
H3PO4(aq) ←→ 3 H+(aq) + PO4–(aq)
b. Basa lemah
M(OH)x(aq) ←→ Mx+(aq) + x OH–(aq)
Contoh: NH4OH(aq) ←→ NH4+(aq) + OH–(aq)
Al(OH)3(aq) ←→ Al3+(aq) + 3 OH–(aq)
Fe(OH)2(aq) ←→ Fe2+(aq) + 2 OH–(aq)
