Diketahui Kb NH₃ = 1,8 × 10⁻⁶, tentukan: Tetapan hidrolisis (Kh) larutan garam NH₄I 0,1 M

Diketahui Kb NH₃ = 1,8 × 10⁻⁶, tentukan:
Tetapan hidrolisis (Kh) larutan garam NH₄I 0,1 M

Kh larutan garam tersebut adalah 5,56×10^-9.

Ayo simak pembahasan berikut agar lebih paham.

Tetapan hidrolisis (Kh) garam merupakan hasil pembagian dari tetapan kesetimbangan air (Kw) terhadap Ka (pada garam basa) dan terhadap Kb (pada garam asam).

NH4I adalah garam terhidrolisis parsial bersifat asam, sehingga harga Kh dihitung sebagai berikut.
Kh = Kw / Kb
Kh = 10^-14 / 1,8×10^-6
Kh = 5,56×10^-9

Jadi, Kh larutan garam tersebut adalah 5,56×10^-9.
