The concentration of hydrogen ions determines the pH. Since water is neutral with a pH of 7 or so, any substance with a lower concentration is acidic.
Lower concentrations of H+ ions indicate a basic solution. Pure water has a neutral pH, so any solution with a lower concentration of H+ ions than pure water would be considered basic. Acidity increases as the concentration of H+ ions in a solution increases.
An acidic solution has a lower pH value (below 7) compared to pure water which has a neutral pH of 7. Acids in the solution will increase the concentration of hydrogen ions (H+) and decrease the concentration of hydroxide ions (OH-), resulting in a more corrosive and sour taste.
The pH value of pure water is 7 because it is neutral, meaning it has an equal concentration of hydrogen ions (H+) and hydroxide ions (OH-). In pure water, the self-ionization process creates an equilibrium where the concentrations of H+ and OH- ions are equal, resulting in a neutral pH of 7.
In pure water, the ratio of H+ ions to OH- ions is 1:1, resulting in a neutral pH of 7. This is due to the self-ionization of water, where water molecules can donate and accept protons to maintain this balance.

acids
The pH of a solution is a measure of the concentration of hydrogen ions (H+) in the solution. Pure water has a pH of 7, indicating a neutral solution with equal concentrations of H+ and OH- ions. If a solution has a higher concentration of H+ ions than pure water, its pH would be less than 7, making it acidic. The lower the pH value, the higher the acidity of the solution.
Using the terms "pOH and pH" is not a way to express the hydroxide and hydronium ion concentrations in pure water at 25 degrees Celsius. At 25 degrees Celsius, the concentrations of hydroxide and hydronium ions in pure water are equal: 1.0 x 10^-7 M.
Pure water has a pH of 7 because it is neutral, with equal concentrations of hydrogen ions (H+) and hydroxide ions (OH-) due to the self-ionization of water. This balance of ions gives rise to a pH level of 7, indicating a neutral solution.

One way to express the hydroxide and hydronium ion concentrations in pure water at 25°C is through the equation Kw = [H3O+][OH-], where Kw is the ion product constant for water. The concentration of hydronium ions ([H3O+]) is equal to the concentration of hydroxide ions ([OH-]) at 25°C, which is 1.0 x 10^-7 mol/L.
