The highest pH value in a group of such values indicates that the greatest concentration of hydroxide ions is present in the substance with the highest pH. This is true because a higher pH indicates a lower concentration of hydrogen ions, and the product of the molar concentrations of hydrogen and hydroxide ions must always be 10-14 at standard temperature and pressure in a mixture that is mostly water.
OH- and H+
Dispersion & Dissociation
In aqueous solutions, most bases contain hydroxide ions (OH-) as the active ingredient. These hydroxide ions are responsible for the basic properties of the solution, such as their ability to accept protons (H+) from acids.
No, you mixed it up. Hydronium H3O+ from strong acid and Hydroxide OH- from strong base (alkaline)
The pH of a 0.1 M solution of sodium hydroxide would be around 13-14, as it completely dissociates in water to produce hydroxide ions, resulting in a high concentration of OH- ions and a basic pH.
Hydroxide (OH-)
Most bases taste bitter and give off hydroxide ions. Examples include sodium hydroxide and potassium hydroxide. These strong bases completely ionize to form the metal and hydroxide ions in solution are very corrosive.

Yes, rubidium hydroxide (RbOH) is soluble in water. As an alkali metal hydroxide, it dissociates readily in water to form rubidium ions (Rb⁺) and hydroxide ions (OH⁻), making the solution alkaline. This high solubility is characteristic of most alkali metal hydroxides.
The most common chemical method for removing hydrogen ions in a solution is by using a base, such as sodium hydroxide or potassium hydroxide. Bases, due to their alkaline nature, can react with hydrogen ions (protons) to form water molecules, effectively neutralizing the acidity of the solution and increasing its pH.
When copper react with sodium hydroxide, copper hydroxide is one of the products which has a distinct colour, so... 1) Add a few drops of dilute sodium hydroxide to the solution you wish to test for copper ions 2) If a blue precipitate forms (copper hydroxide is insoluble in water), then it's likely that copper ions are present 3) To confirm the presence of copper ions, add ammonia solution & if the precipitate dissolves, forming a deep blue solution, you know copper ions are present
A solution of sodium hydroxide in water will have a pH close to 14, as sodium hydroxide is a strong base that dissociates completely in water to produce hydroxide ions, increasing the pH.
