Macam Macam Electrolit Lemah dan Kuat

Macam Macam Electrolit Lemah dan Kuat


1. Elektrolit Kuat

a. Asam kuat

HxZ (aq)-> x H+(aq) + Zx–(aq)

Contoh:

• HCl(aq)-> H+(aq) + Cl–(aq)

• H2SO4(aq)->2 H+(aq) + SO42–(aq)

• HNO3(aq)-> H+(aq) + NO3–(aq)

b. Basa kuat

M(OH)x(aq)-> Mx+(aq) + x OH–(aq)

Contoh:

• NaOH(aq)-> Na+(aq) + OH–(aq)

• Ba(OH)2(aq)-> Ba2+(aq) + 2 OH–(aq)

• Ca(OH)2(aq)-> Ca2+(aq) + 2 OH–(aq)

c. Garam

MxZy(aq)-> x My+(aq) + y Zx–(aq)

Contoh:

• NaCl(aq)-> Na+(aq) + Cl–(aq)

• Na2SO4(aq)->2 Na+(aq) + SO42–(aq)

• Al2(SO4)3(aq)->2 Al3+(aq) + 3SO42–(aq)





2. Elektrolit Lemah

a. Asam lemah

HxZ(aq) ightleftharpoons x H+(aq) + Zx–(aq)

Contoh:

CH3COOH(aq) ightleftharpoons H+(aq) + CH3COO–(aq)

H2SO3(aq) ightleftharpoons 2 H+(aq) + SO32–(aq)

H3PO4(aq) ightleftharpoons 3 H+(aq) + PO4–(aq)

b. Basa lemah

M(OH)x(aq) ightleftharpoons Mx+(aq) + x OH–(aq)

Contoh:

NH4OH(aq) ightleftharpoons NH4+(aq) + OH–(aq)

Al(OH)3(aq) ightleftharpoons Al3+(aq) + 3 OH–(aq)

Fe(OH)2(aq) ightleftharpoons Fe2+(aq) + 2 OH–(aq)
