An aqueous solution that contains more hydroxide ions than hydrogen ions is considered a basic solution with a pH greater than 7. This solution is known as an alkaline solution and has a higher concentration of hydroxide ions, making it a stronger base.
If the solution is basic, there are more hydroxide ions than hydrogen ions. In an acidic solution, there are more hydrogen ions than hydroxide ions. The balance between these ions determines the pH of a solution.
A neutral solution, such as pure water, contains an equal number of hydrogen ions (H+) and hydroxide ions (OH-). This creates a balance that maintains a pH of 7, indicating that the solution is neither acidic nor basic.
A solution with more hydroxide ions than hydrogen ions is basic in nature. It has a pH above 7, indicating it is alkaline. Examples include solutions of sodium hydroxide or potassium hydroxide.
Basic solutions are solutions that have more than a 1E-7 concentration of hydroxide ion. Thus, solutions with "extra" hydroxide ions are basic. On the other hand, solutions with extra hydrogen (hydronium) ions are acidic.

Solutions with a pH greater than 7 have a greater number of hydroxide ions (OH-) than hydrogen ions (H+). This indicates that the solution is basic or alkaline.
An acid contains more hydrogen ions than hydroxide ions. Acids release hydrogen ions (H+) in water, while bases release hydroxide ions (OH-).
A base does this. The hydroxide (OH-) ion appears in solution. An acid produces hydrogen (or hydronium) ions in solution, and not hydroxide ions.
A neutral solution has an equal number of hydronium ions (H3O+) and hydroxide ions (OH-) present, resulting in a balanced pH of 7. This equilibrium reflects the concentration of hydrogen ions being equal to the concentration of hydroxide ions in the solution.
Basic or alkaline or greater than pH 7
In a solution with a pH of 4, the concentration of hydrogen ions (H+) is higher than the concentration of hydroxide ions (OH-). The pH scale is logarithmic, so a pH of 4 indicates that the concentration of hydrogen ions is 10^-4 moles per liter, while the concentration of hydroxide ions can be calculated using the water dissociation constant (Kw).
A neutral solution, such as pure water, contains equal concentrations of hydrogen (H+) and hydroxide (OH-) ions. At 25°C, their concentrations are both 1.0 x 10^-7 mol/L.
