Is H3O Lewis acid or base?
A basic solution has more OH- ions A solution with more H3O+ is acidic.
What happens to OH in an aqueous solution when H3O increases?
it decreases
A neutral solution of a salt in water contains?
an equal number of H3O+ ions and OH- ions
What equilibrium reaction determines OH and therefore the pH of the solution?
Water ampholytic (acid+base) equilibrium: H2O + H2O <--> H3O+ + OH-
What is pH of a substance?
The pH of a substance tells if it's an acid, neutral, or a base. With all deference to the asker and to the previous answerer, technically substances don't have pH's. Aqueous solutions have pH's, and the pH tells you (on a logarithmic scale) the concentration of H+ (or more precisely H3O+) in that solution. A substance is an acid if it lowers the pH of a solution when it is dissolved. It does this by donating protons (H+'s) to water molecules to create more H3O+. A substance is a base if it increases the pH of a solution by accepting a proton from water molecules to form OH-. H3O+ and OH- are in equilibrium with each other in solution, so the more OH- you create, the less H3O+ will be in solution and the higher the pH. So a better answer to the question is that "The pH of a solution tells you if its an acidic, neutral, or basic solution."
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 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.

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.

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)
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.
Why would H plus and OH- in water recombine after they break up?
This is an acid base reaction. H+ actually becomes H3O+ when other water molecules are present. Why H3O+ + OH− recombine to form 2H2O completely depends on what other chemicals are present in the solution. The hydronium ion concentration multiplied by the hydroxide concentration is a constant, 10-14. That is, [H3O+]*[OH-]=10-14. So if more acid is added to the solution, H3O+ + OH− will combine to form two water in order to meet the criteria stated above. http://en.wikipedia.org/wiki/Acid%E2%80%93base_reaction
Is H3O 1.6 x 10-9 a basic solution?
- log(1.6 X 10 -9 M) = 8.8 pH ================rather a small concentration of H3O, so, yes. OH - is high.
