Mula : 10 5 -
Reaksi : -5 -5 + 5
Sisa : 5 - 5
[H+] = Ka x na/b.nbasa konjugasi
= 10-5 x 5/2x5
= 10-5 x 5/10
= 0,5 x 10-5
= 5 x 10-6
pH = -log [H+]
= - log 5 x 10-6
= 6 –log 5
= 6 – 0,7
= 5,3
nBa(OH)2 = 0,1 x 50 = 5mmol
CH3COOH + Ba(OH)2 -------> CH3COOBa + H2O

[H+] = Ka x a/g = = 10-5 x 5/2x5
= 10-5 x 5/10
= 0,5 x 10-5
= 5 x 10-6
pH = -log [H+]
= - log 5 x 10-6
= 6 –log 5
= 6 – 0,7
= 5,3<------ jumlah pH campuran. maaf klo ga bener :3
