Question

Hitunglah ph campuran antara 200 mL larutan CH3COOH 0,15 M dengan 150 ML larutan NaOH 0,10 M , (Ka CH3COOH=10-5
mohon diisi ya soal kimia penyangga

Answer 1

Molaritas CH3COOH = 200 x 0,15 = 30 mmol
molaritas NaOH = 150 x 0,1 = 15 mmol

    CH3COOH + NaOH -> CH3COONa + H2O
M.....30..............15..............................
R.....-15.............-15............+15............
A......15..............................15..............
