What is the pH of a 10-5 m of koh solution?
The pH of a 10^-5 M KOH solution would be around 9. For a given concentration of a strong base like KOH, the pH can be calculated using the formula pH = 14 - pOH. Given that pOH = -log[OH-] and [OH-] = 10^-5 M in this case, pOH = 5. Therefore, pH = 14 - 5 = 9.
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?
To find the H ion concentration in a KOH solution, first determine the hydroxide ion (OH-) concentration. Since KOH is a strong base, it fully dissociates in water. Therefore, the OH- concentration is equal to the KOH concentration, which is 4.8x10^-2 M. The H ion concentration can be calculated using the equation Kw = [H+][OH-], where Kw is the ion product of water (1.0x10^-14 at 25°C). From there, you can determine the H ion concentration by dividing Kw by the OH- concentration.
When the H in a solution is 1.7 109 M what is the pOH?
The pOH is 5,23.
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 '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?
To calculate the concentration of hydroxide ions (OH-) from a given pH value, you can use the formula: [OH-] = 10^(-pH). For a pH of 1.12, the concentration of hydroxide ions would be [OH-] = 10^(-1.12) = 0.079 moles per liter.

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?
To calculate the mass of KOH needed to make 400mL of 725 M KOH solution, you would use the formula: mass = volume (in L) * molarity * molar mass First, convert the volume from mL to L (400mL = 0.4 L). Then plug in the values for volume (0.4 L), molarity (725 M), and the molar mass of KOH (39.10 g/mol) to find the mass of KOH needed. mass = 0.4 L * 725 mol/L * 56.11 g/mol ≈ 131.78 grams.
If pH is 6 What is is OH?
To find the concentration of hydroxide ions (OH-) at pH 6, you can use the formula: OH- concentration = 10^-(14-pH). So, at pH 6, the concentration of OH- would be 1 x 10^-8 moles per liter.
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
