[H3O+][OH-] = Kw = 1x10^-14
[OH-] = 1x10^-14/0.0034 = 1x10^-14/3.4x10^-3
[OH-] = 2.9x10^-12 M

Which pH indicates the highest concentration of H3O?
The pure water has the pH=7; the concentrations of OH- and H3O + are equivalent.
What is the product of H3O ion and OH- ion concentration in water?
10^-14
What are the H3O plus and OH- for a solution with the following pH value 10.0?
pH=10, means the concentration of OH- ions is 0.0001 M and concentration of H+ ions is 0.0000000001M
The ph of lemon juice at 298 k is found to be 2.32 what is the concentration oh H3O plus ions in the solution?
If the PH of lemon juice at 298 k is found to be 2.32, the concentration of H3O plus ions in the solution would be 0.5 M.
Name the products of the dissociation of water and give their concentration in pure water?
2H2O H3O^+1 + OH^-1at 25 deg C, [H3O+] = [OH-] = 1x10^-7 mol/LH3O^+1 = hydronium ionOH^-1 = hydroxide ion
How is the Kw constant developed?
it is the concentration of H3O+ times the concentration of OH-
The following are pH values cola 2 orange juice 3 beer 4 coffee 5 human blood 7.4 Which of these liquids has the highest molar concentration of OH?
The pH is a measure of the concentration of H3O+ in a solution. The lower the pH, the higher the concentration of H3O+. This is because of the way it is defined:pH = - log10 [H3O+]or in other words, the pH is the negative logarithm (in base 10) of the concentration of H3O+.Water, and water-based solutions have a special property: if you multiply the concentration of H3O+ and the concentration of OH-, you always get a constant number, no matter what. Mathematically, that is:[H3O+] * [OH-] = 1 x 10-14This also says the the two concentrations are inverselyproportional. So when one is high, the other has to be low.So, getting back to your question, we know the pH of each solution. From that we know the concentration of H3O+. Again, lower the pH, the higher the concentration of H3O+. And since the concentrations of H3O+ and OH- are inversely proportional, when H3O+ is high, the OH- concentration is low. So which solution has the lowest amount of H3O+? That's the one that has the highest pH, and that will also have the highest concentration of OH-.See the Related Questions for more information about pH, acids and bases.

What statements correctly describes the hydronium-hydroxide balance in the given solution?
In neutral solutions, [H3O+] = [H2O].In bases, [OH-] = [H3O+].In bases, [OH-] is greater than [H3O+].In acids, [OH-] is greater than [H3O+].In bases, [OH-] is less than [H3O+].
What is the product of H3O ion and OH- ion concentration in water?
10^-14
What is the difference between an acid and a base and something that is neutral?
The difference between the three is the relative concentration of H3O+ and OH- in the solution.An acid solution has a higher concentration of H3O+ than OH- and its pH is lower than 7.A basic solution has a higher concentration of OH- than H3O+ and its pH is higher than 7.A neutral solution has exactly equal concentration of each one and its pH is exactly 7.
What is the symbol for hydronium?
Hydronium is the protonated water molecule: H3O+It is found in pure water formed by autoprotolysis, at concentration of 1.0*10-7 mol/L:H2O + H2O
What are the H3O plus and OH- for a solution with the following pH value 10.0?
pH=10, means the concentration of OH- ions is 0.0001 M and concentration of H+ ions is 0.0000000001M
Do antacids neutralize acidity?
Antacid molecules dissociate in the stomach into some R+ group and an OH- group (hydroxide). The hydroxide reacts with an H3O+ ion (hydronium) to form two H2O molecules. The reduction in H3O+ concentration corresponds to increased pH (decreased acidity). 1) ROH -> R+ + OH- 2) OH- + H3O+ -> 2H2O pH = -ln([H3O+])/ln(10)
A dynamic equilibrium is reached when hydrogen cyanide acid is dissolved in water Which species is present in the highest concentration in this solution?
C2H3O2-(aq) H+(aq) H3O+(aq) OH-(aq) HCN(aq)Those are the choices that could be given, but the answer is HCN. It can't be H+ or OH- because the water is de-ionized and H3O+ is not possible.
The ph of lemon juice at 298 k is found to be 2.32 what is the concentration oh H3O plus ions in the solution?
If the PH of lemon juice at 298 k is found to be 2.32, the concentration of H3O plus ions in the solution would be 0.5 M.
