https://en.wikipedia.org/wiki/Base_(chemistry)
WebIn the more general Brønsted–Lowry acid–base theory (1923), a base is a substance that can accept hydrogen cations (H + )—otherwise known as protons. This does include aqueous hydroxides since OH − does react with H + to form water, so that Arrhenius bases are a subset of Brønsted bases.

WebBases. Bases have properties that mostly contrast with those of acids. Aqueous solutions of bases are also electrolytes. Bases can be either strong or weak, just as acids can. Bases often have a bitter taste and are found in foods less frequently than acids. Many bases, like soaps, are slippery to the touch. Bases also change the color of ...
