Base | Definition, Examples, & Facts | Britannica
WEBbase, in chemistry, any substance that in water solution is slippery to the touch, tastes bitter, changes the colour of indicators ( e.g., turns red litmus paper blue), reacts with acids to form salts, and promotes certain chemical reactions (base catalysis).
What Is a Base in Chemistry? Definition and Examples
WEBJun 19, 2021 · In chemistry, a base is a substance that reacts with acids to form a salt and which releases hydroxide ions, accepts protons, or donates electrons in aqueous solution. Learn about the properties of bases and see examples of bases and their uses.
Base (chemistry) - Wikipedia
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.

WEBApr 5, 2021 · Bases. A base can be simply defined as an ionic compound that produces hydroxide ions when dissolved in water. One of the most commonly used bases is sodium hydroxide, illustrated below. Figure 7.4.1 7.4. 1: (A) Sodium hydroxide, a base, is a solid that is typically produced as small white pellets.

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 ...

WEBSep 29, 2022 · Anne Marie Helmenstine, Ph.D. Updated on September 29, 2022. In chemistry, a base is a chemical species that donates electrons, accepts protons, or releases hydroxide (OH-) ions in aqueous solution. Bases display certain characteristic properties that can be used to help identify them.
