bantuin dong soal kimia

▶ Langkah pertama cari jumlah mol masing2 larutan .
Jumlah mol CH3COOH = M x V = 0,1 x 100 = 10 mmol
Jumlah mol CH3COOHNa = M x V = 0,1 x 200 = 20 mmol

▶ langkah kedua mencari [H+]
[H+] = ka x a/g
= 10^-5 x 10/20
= 5 x 10^-6

▶ langkah terakhir menghitung PH
PH = - log [H+]
= - log 5 x 10^-6
= 6 - log 5

Semoga membantu;))
