If the concentration of H3O+ and OH- ions are equal, the solution is neutral with a pH of 7. This is because in neutral water, the concentration of H3O+ ions (from dissociation of water) is equal to the concentration of OH- ions.
To determine the concentrations of H3O and OH- ions from the pH of a solution, you can use the formula: pH -logH3O. From this, you can calculate the concentration of H3O ions. Since the product of H3O and OH- ions is constant in water (1.0 x 10-14 at 25C), you can then find the concentration of OH- ions by dividing this constant by the concentration of H3O ions.
To find the OH- concentration in water when you know the H3O+ concentration, you can use the formula Kw = [H3O+][OH-]. Given that Kw (at 25°C) is 1.0 x 10^-14, you can rearrange the equation to solve for OH-. In this case, [OH-] = Kw / [H3O+] which would equal 2.94 x 10^-12 M.
The product of the H3O+ ion concentration and the OH- ion concentration in water is always equal to the ion product of water, which is 1.0 x 10^-14 at 25°C. This relationship is described by the equation [H3O+][OH-] = 1.0 x 10^-14.
The pure water has the pH=7; the concentrations of OH- and H3O + are equivalent.
A substance with a higher concentration of H3O+ ions would be an acidic solution. In acidic solutions, the concentration of H3O+ ions is greater than the concentration of OH- ions, leading to a lower pH value. Substances like hydrochloric acid or sulfuric acid are examples of substances with a high concentration of H3O+ ions.
The concentration of OH- for a solution with H3O+ concentration of 1x10^-5 M can be found by using the ion product constant of water (Kw = 1.0x10^-14) to calculate the OH- concentration. Since H3O+ and OH- are related by Kw = [H3O+][OH-], you can solve for [OH-] by rearranging the equation. This will give you a value of 1.0x10^-9 M for the OH- concentration.

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.

Substances like hydrochloric acid or sulfuric acid are examples of substances with a high concentration of H3O+ ions.
As the concentration of H₃O⁺ increases in an aqueous solution, the pH decreases, shifting the equilibrium of the autoionization of water to the left. This results in a decrease in the concentration of hydroxide ions (OH⁻) in the solution.
In pure water, the concentration of H3O plus (hydronium ion, H3O+) is 1.0 x 10^-7 mol/L and the concentration of OH- (hydroxide ion) is also 1.0 x 10^-7 mol/L. This represents a balanced state of neutrality.
The concentration of H3O+ can be calculated using the equation Kw = [H3O+][OH-]. Given that Kw = 1.0 x 10^-14, and [OH-] = 4.54 x 10^-6 M, you can solve for [H3O+] to find that it is approximately 2.2 x 10^-9 M.
The hydronium-hydroxide balance in a solution is determined by the concentration of H+ ions (hydronium) and OH- ions (hydroxide). In a neutral solution, the concentrations of H+ and OH- ions are equal and the solution is considered neutral. In an acidic solution, the concentration of H+ ions is higher than OH- ions, resulting in a lower pH. In a basic solution, the concentration of OH- ions is higher than H+ ions, resulting in a higher pH.
pH=10, means the concentration of OH- ions is 0.0001 M and concentration of H+ ions is 0.0000000001M
