The pH of a solution is a measure of the concentration of hydronium ions (H3O+) present. A lower pH value indicates a higher concentration of H3O+ ions, making the solution more acidic. Conversely, a higher pH value indicates a lower concentration of H3O+ ions, making the solution more basic.
The concentration of hydronium ions ([H3O+]) is directly related to pH through the formula pH = -log[H3O+]. A lower pH value indicates a higher concentration of hydronium ions, and a higher pH value indicates a lower concentration of hydronium ions in a solution.
The pure water has the pH=7; the concentrations of OH- and H3O + are equivalent.
The pH of a solution with a H3O+ concentration of 7.9x10-11 M is approximately 10.1. This is because pH is calculated as -log[H3O+], so -log(7.9x10-11) ≈ 10.1.
The pH of the solution can be calculated using the formula: pH = -log[H3O+]. Substituting the given value of [H3O+] = 2 x 10^-4M into the formula, pH = -log(2 x 10^-4) = 3.7. Therefore, the pH of the solution is 3.7.
By definition: pH = -log[H3O+]So pH = -log(7.4*10-9) = 8.13
The concentration of hydronium ions ([H3O+]) is directly related to pH through the formula pH = -log[H3O+]. A lower pH value indicates a higher concentration of hydronium ions, and a higher pH value indicates a lower concentration of hydronium ions in a solution.

The concentration of H3O+ (hydronium ions) in a solution can be calculated using the formula pH = -log[H3O+], where [H3O+] represents the molarity of the hydronium ions. This formula relates the acidity of a solution to the concentration of hydronium ions present.
3. since the [H+]=0.001 M then pH= -log[H+] -log(0.001)=3 pH=3.
The concentration of an acid or base is measured in terms of the pH scale, which indicates the presence of H3O+ ions in solution. A lower pH value indicates a higher concentration of H3O+ ions, representing a more acidic solution. A higher pH value indicates a lower concentration of H3O+ ions, representing a more basic solution.
The pH of a solution with an H3O+ concentration of 1 x 10^-5 M is 5. This is because pH is defined as -log[H3O+], so by taking the negative logarithm of 1 x 10^-5, the pH is 5.
pH = (by definition) = -log10[H3O+] , no matter what kind of acid,This inverted to:[H3O+] = 10-pH = becomes 10-2.9 = 1.3*10-3 mol/lNote: [H3O+] = concentration of hydronium ions (mol/l),which is the same as (or equivalent with) saying H+ ions concentration in water
The pH of the solution can be calculated from the hydronium ion concentration using the formula pH = -log[H3O+]. Plugging in the value given (H3O+ = 10^-14 M) gives a pH of 14.
- log(4.3 X 10 -8 M hydronium ) = 7.4 pH ------------- Indicates that hydronium to hydroxide concentrations are low, so slightly basic solution. About blood pH.
