Tentukan pH larutan-larutan asam kuat berikut ini a. 100Ml HCI 10–² B. Larutan NaOH 0,1 M

A. 100 mL HCl 10-²M
HCl -> H+ + Cl-
10-²M
[H+] = koefisien H+/Koefisien HCl = 1/1 x 10-²M
= 10-²M
pH = -log [H+]
= -log 10-²
= 2

B. Larutan NaOH 0,1 M
NaOH -> Na+ + OH-
0,1M
[OH-] = 0,1 M
pOH = -log [OH-]
= -log 10-¹
= 1
pH = 14 - pOH
= 14 - 1
= 13
