berapakah Ph larutan jika (H+) sebesar 6 x 10-7
Evaluate responses using AI:
OFF
Answer explanation
berapakah Ph larutan jika (H+) sebesar 6 x 10-7
pH = - log (H+)
pH = - log (6 x10-7)
pH = 7 - log 6
pH = 7 - 0,7
pH = 6,3

berapakah pH larutan jika (OH) sebesar 2 x 10-3
Evaluate responses using AI:
OFF
Answer explanation
berapakah pH larutan jika (OH) sebesar 2 x 10-3
pH = pKw - pOH
pOH = - log (OH-)
pOH = - log ( 2 x 10 -3)
pOH = 3- log 2
pOH = 3 - 0,3
pOH = 2,7
maka pH = 14- 2,7
pH = 11,3

berapa nilai (-OH) suatu larutan yng memiliki pH 6
Evaluate responses using AI:
OFF
Answer explanation
berapa nilai (-OH) suatu larutan yng memiliki pH 6
pH = pKw - pOH
6 = 14 - pOH
pOH = 14 - 6
pOH = 8
pOH = - log (OH-)
8 = -log(OH-)
OH- = 10-8
