There are Bronsted-Lowry bases and Lewis bases... Brønsted bases accept protons (H+) and Lewis bases donate electrons... So something like H2O + H2O--> H3O (hydronium) + -OH would mean that H2O is a Bronsted base and acid. You have to look at it in context.
A base is a compound that produces hydroxide ions (OH-) in solution.
A base.
A base in solution will produce hydroxide or OH- ions.
The compound is a base.
Phosphoric acid is the most common substance that produces three hydrogen ions in solution
a base
A base.
base
yes
It Produces a hydroxide ion
A base in solution produces hydroxide ions (OH-) as the predominant ion.
A base is a substance that can accept protons, while a basic solution is a solution with a pH greater than 7 due to the presence of a base. Bases help to increase the concentration of hydroxide ions in a solution, leading to a basic pH.
