What is the pH of a 0.04 M KOH solution?
0.04 M KOH produces an OH- concentration of 0.04 M. Thus, the pOH is -log 0.04 = 1.4 and the pH will be 14 - 1.4 = 12.6
What is the pH of a 1.0 10-3 M KOH solution?
[OH-] = 1x10^-3 M[H+][OH-] = 1x10^-14[H+] = 1x10^-14/1x10^-3 = 1x10^-11pH = -log 1x10^-11 = 11Done another way:pOH = -log [OH-] = -log 1x10^-3 = 3pH + pOH = 14pH = 14 - 3 = 11
What is the H ion concentration in a 4.8x10-2 M KOH solution?
pOH = -log(10)[OH^-] pOH = -log(10) [ 48. x 10^-2] pOH = - (-1.31875...) pOH = 1.31875... pH = 14 - pOH pH = 14 - 1.31875... pH = 12.68124... pH = 12.68
When the H in a solution is 1.7 109 M what is the pOH?
The pOH is 5,23.
If the pH of a solution is 10.7, what would the pOH be?
The pOH is 6,4.
What is the pH of a 0.04 M KOH solution?
0.04 M KOH produces an OH- concentration of 0.04 M. Thus, the pOH is -log 0.04 = 1.4 and the pH will be 14 - 1.4 = 12.6
What is the pH of a 1.0 10-3 M KOH solution?
[OH-] = 1x10^-3 M[H+][OH-] = 1x10^-14[H+] = 1x10^-14/1x10^-3 = 1x10^-11pH = -log 1x10^-11 = 11Done another way:pOH = -log [OH-] = -log 1x10^-3 = 3pH + pOH = 14pH = 14 - 3 = 11
What is the H ion concentration in a 4.8x10-2 M KOH solution?
pOH = -log(10)[OH^-] pOH = -log(10) [ 48. x 10^-2] pOH = - (-1.31875...) pOH = 1.31875... pH = 14 - pOH pH = 14 - 1.31875... pH = 12.68124... pH = 12.68
What is 'a poco a poco' when translated from Italian to English?
"Little by little" is an English equivalent of the Italian phrase a poco a poco.Specifically, the preposition a literally means "at, to." The adverb poco means "little." The pronunciation is "ah POH-koh ah POH-koh."
When the H in a solution is 1.7 109 M what is the pOH?
The pOH is 5,23.
How do you calculate OH- with a ph of 1.12?
pH + pOH = 14. So pOH = 14 - 1.12 = 12.88 pOH = -log[OH-] [OH-] = 1.31 x 10-13 M
Anu ano ang uri ng panahon mayroon ang unang Filipino?

What is 'cosmopolitan' in Italian?
Cosmopolitano is an Italian equivalent of 'cosmopolitan'. It's the masculine form of an adjective whose feminine equivalent is 'cosmopolitana'. Both forms are pronounced 'koh-smoh-poh-lee-TAH-no' and 'koh-smoh-poh-lee-TAH-nah', respectively.no, it's "cosmopolita" for both gender.
If the pH of a solution is 10.7, what would the pOH be?
The pOH is 6,4.
What mass of KOH is needed to make 400mL of 725 M KOH?
I assume you mean 7.25 M KOH, but the process is the same anyway.Molarity = moles of solute/Liters of solution ( 400 ml = 0.4 Liters )7.25 M KOH = X moles KOH/0.4 Liters= 2.9 moles KOH (56.108 grams/1 mole KOH)= 163 grams potassium hydroxide needed===============================
If pH is 6 What is is OH?
pH + pOH = 14. So pOH = 14 - 6 = 8 pOH = -log[OH-] [OH-] = 10-8 M
How many moles of KOH are contained in 750. mL of 5.00 M KOH solution?
Molarity = moles of solute/volume of solution 0.500 M KOH = moles KOH/125 ml 62.5 millimoles, or to answer the question precisely, 0.0625 moles KOH
