base, 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).
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 Definition
A base is a substance that forms hydroxide ions OH-when dissolved in water. For example, hydrochloric acid (\(\ce{HCl}\)) is an acid because it forms \(\ce{H^{+}}\) when it dissolves in water. \[\mathrm{HCl}(\mathrm{g}) \stackrel{\text { Water }}{\longrightarrow} \mathrm{H}^{+}(\mathrm{aq})+\mathrm{Cl}^{-}(\mathrm{aq})\nonumber\]
In chemistry, there are three definitions in common use of the word " base ": Arrhenius bases, Brønsted bases, and Lewis bases. All definitions agree that bases are substances that react with acids, as originally proposed by G.-F. Rouelle in the mid-18th century.
In the field of chemistry, a ‘base’ can be defined as a substance that releases hydroxide ions when dissolved in aqueous media. Learn about the properties of bases with examples and FAQs.
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.
A base is thought of as a substance which can accept protons or any chemical compound that yields hydroxide ions (OH-) in solution. It is also commonly referred to as any substance that can react …
Bases are substances that taste bitter and feel slippery when touched. In chemistry, they are known for turning red litmus paper blue and are commonly found in household items like baking soda and soap. Bases react with acids to form water and salts, a process called neutralization.
By. Anne Marie Helmenstine, Ph.D. Updated on May 05, 2019. There are several methods of defining acids and bases. While these definitions don't contradict each other, they do vary in how inclusive they are. The most common definitions of acids and bases are Arrhenius acids and bases, Brønsted-Lowry acids and bases, and Lewis acids and bases.
In chemistry, a base is defined as a molecule in an aqueous solution that can accept protons or donate electrons. They often taste bitter and are slippery to the touch....
