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.
What else can I help you with?
Which symbols below represent the ions found in glass of water?
OH- and H+
Most acids form ions in solution by , and most bases form ions in solution by?
Dispersion & Dissociation
What does aqueous solutins contain in most bases?
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.
Does a strong base produce the most hydronium ions in an aqueous solution?
No, you mixed it up. Hydronium H3O+ from strong acid and Hydroxide OH- from strong base (alkaline)
Given that sodium hydroxide is a strong base what is most likely its pH?
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.
What ions do most basic compounds contain?
Hydroxide (OH-)
What is a substance that tastes bitter and gives off hydroxide ions in a reaction?
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.
What will most readily form hydroxide ions in water?
Any kind of base

Is RbOH soluble in water?
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.
What is the most common chemical method for removing hydrogen ions in a solution?
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.
How do you test for copper ions?
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 is most likely to have a pH close to?
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.
