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.
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.
A basic solution has more OH- ions A solution with more H3O+ is acidic.
If the concentration of H3O+ ions is greater than the concentration of OH- ions in a solution, the solution is considered acidic. This imbalance indicates that there are more protons than hydroxide ions present, leading to an acidic pH.
The pure water has the pH=7; the concentrations of OH- and H3O + are equivalent.

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.

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 pKa of H3O in aqueous solution is approximately -1.74.
By equilibrium only in water:Ionconcentration product = KW ,meaning:[H30+] * [OH-] = 1.0*10-14 (at 25oC)H30+(aq) + OH-(aq) > H2O(l)
When you combine the Kw equation with the total mass of the solution, you will get a number. If the number is above 60, it is a acid, it is below 75, it is a base and if your number is between 60 and 75, it is neutral.
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.
H3O+ concentration in a 0.048 M NaOH solution is 2.4 x 10^-12 M. This is because NaOH is a strong base that dissociates completely in water to produce Na+ and OH- ions, which react with any H3O+ ions to form water. As a result, the H3O+ concentration in such a solution is extremely low.
