mol H2CO3 = 0,1*100=10 mmol
direaksikan dulu
NH4OH + H2CO3 --> NH4CO3+H2O
M 2O 10 - -
R 10 10 10 10
S 10 - 10 10
buffer basa
OH- = Kb.nB per nG
= 1,8 . 10 pangkat -5 . 10 per 10
= 1,8 . 10 pangkat -5 = 18 . 10 pangkat -6
pOH = - log 18 . 10 pangakt -6
= - log 18 +(-log 10 pangkat -6)
= 6 - log 18
pH = 14 - ( 6 - log 18 )
= 8+ log 8
maaf kalo salah. dicek lagi ya
