Kimia kelas 10 SMA Larutan Asam Basa. Anak SMA jawab ini ya! JAWAB YA NO.3 C DAN D! PAKAI CARA YA KALO BISA! Anak SD dan SMP dilarang jawab ini ya, kalo anak S

c.
HNO3 → H+ + NO3-

[H+] = n . M
[H+] = 1 . 0,01M
[H+] = 10^-2

pH = -log [H+]
pH = -log10^-2
pH = 2

d.
[OH-] = √Kb . M
[OH-] = √9 x 10^-7 x 4 x 10^-3
[OH-] = √36 x 10^-10
[OH-] = 6 x 10^-5

pOH = - log[OH-]
pOH = -log 6 x 10^-5
pOH = 5 - log6

pH = 14 - (5 - log6)
pH = 14 - 5 + log6
pH = 9 + log6
