Tentukan pH larutan sebelum dicampur dan sesudah dicampur jika 100 mL larutan H2SO4 0,1 M direaksikan dengan 100 mL larutan KOH 0,1 M
PEMBAHASAN :
pH sebelum dicampur
pH H2SO4 (asam kuat)
[H+] = a. Ma = 2 . 10-1 M
pH = 1 – log 2
pH KOH (basa kuat)
[OH–] = b. Mb = 1 . 10-1 M
pOH = 1, pH = 14 – 1 = 13
PH sesudah dicampur
n H2SO4 = M x V = 0,1M x 100 ml = 10 mmol
n KOH = M x V = 0,1M x 100 ml = 10 mmol
