a. 50 mL larutan NH3 0,2 M + 100 mL larutan N,1 M; Kb NH3 = 1 x 10^5
b. 150 mL larutan CH3COOH 0,1 M + 100 mL larutan NaOH 0,1 M; Ka CH3COOH = 1 x 10^5
raeksi nya juga yaa…!
1. Hitunglah pH larutan yang terbentuk dari campuran berikut :
B. CH3COOH + NaOH > CH3COONA + H2O
(H+) = KA . 5/1.10
(H+) = 1X10^5 X 1/2
(H+) = 1/2X10^5
PH= – LOG 1/2X10^5
PH = 5-LOG 1/2
