Friends please help me pakai cara yah tugas dari sekolah nih Jika, 0,1 gr NaOH (Mr: 40) dilarutkan kedalaam250 ml air, maka pH larutan adalah... Thank You

Iya dibantu. n = gram/Mr n = 0,1/40 n = 0,025 mol M = n/v M = 0,025/0,25 M = 0,1 M [OH-] = M . ValensiBasa [OH-] = 0,1 . 1 [OH-] = 10pangkat-1 pOH = 1 pH = 14 - pOH pH = 14 - 1 pH = 13

maafyah yang 14 itu dpat dri mana? :D soalnya supaya tay
n = gram/Mr
n = 0,1/40
n = 0,025 mol
M = n/v
M = 0,025/0,25
M = 0,1 M
[OH-] = M . ValensiBasa
[OH-] = 0,1 . 1
[OH-] = 10pangkat-1
pOH = 1
pH = 14 - pOH
pH = 14 - 1
pH = 13
