Does Kw show the interdependence of the H3O plus and OH- in aqueous solutions?
Yes.
How many hydrogen atoms are in CH3COONa plus H2O plus CO2?
Dissolving in water = splitting in ionsCH3COONH4 --> CH3COO- + NH4+CH3COO-, acetate is a weak base: CH3COO- + H2O CH3COOH + OH-NH4+, ammonium is a weak acid: NH4+ + H2O NH3 + H3O+Totally in water: CH3COO- + NH4+ CH3COOH + NH3 and 2H2O H3O+ + 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.
Which molecule represents an ion found in a glass of water?
OH- and H+
How is the Kw constant developed?
it is the concentration of H3O+ times the concentration of OH-
What are the concentrations of H3O plus and OH in pure water?
H3O= 0.9 mol/dm3 OH=1.2 mol/dm3
Copper plus water equals?
Cu+ H2O [OH + H3O= 2H2O]Copper plus more than one water = [CuOH + H3O]
Does Kw show the interdependence of the H3O plus and OH- in aqueous solutions?
Yes.
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+].
How are H3O plus and OH- related?
By equilibrium only in water:Ionconcentration product = KW ,meaning:[H30+] * [OH-] = 1.0*10-14 (at 25oC)H30+(aq) + OH-(aq) > H2O(l)
What substance is the conjugate acid in the reaction HBr plus H2O H3O plus plus Br?
H3o+
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.
Is H3O plus behaving as an acid or base in the following reaction H3PO4 plus H2O H2PO4- plus H3O plus?
In this reaction H3O+ is the conjugate acid. The original acid in this reaction is H3PO4
Is h3o plus acid or base?
H3O is a strong acid.
Prove that Kw equals product of Ka and Kb for an acid-base pair in water?
dissociation of acid in water: A + H2O <-> A- + H3O+ with dissociation constant Ka = [A-][H3O+]/[A][H2O] = [A-][H3O+]/[A]. dissociation of base in water: B + H2O <-> HB+ + OH- with dissociation constant Kb = [HB+][OH-]/[B][H2O] = [HB+][OH-]/[B] dissociation of water in itself: 2H2O <-> H3O+ + OH- with dissociation constant Kw = [H3O+][OH-]/[H2O]^2 = [H3O+][OH-] where [H2O] has been ommitted because it is a pure liquid. substituting relations for Ka and Kb into Kw gives: Kw = [H3O+][OH-] = (Ka[A]/[A-])(Kb[B]/[HB+]) = KaKb where [A] = [HB+] and [B] = [A-].
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
Given that you have a H3O concentration of 0.0034 M what is the OH-?
[H3O+][OH-] = Kw = 1x10^-14[OH-] = 1x10^-14/0.0034 = 1x10^-14/3.4x10^-3[OH-] = 2.9x10^-12 M
