	Acid - Wikipedia, the free encyclopedia
		Neutralization is a type of reaction between an acid and a base.
		Lewis theory defines a "Lewis acid" as an electron-pair acceptor and a "Lewis base" as an electron-pair donor.
		Later on, Brønsted and Lowry defined an acid to be a proton donor and a base to be a proton acceptor.

		In chemistry, a base is the reactive complement to an acid.
		In warfare, a military base is a logistics point such as a supply dump and a concentrated facility for storing and repairing military equipment such as an air force base.
		In topology, a base (topology) for a topology is a set of open sets such that every element of the topology is a union of the base sets.

	Acid-base reaction (from chemical reaction) -- Encyclopædia Britannica
		Acids, bases, and the products of their reactions are vital to many life processes and are valuable to industry.
		More from Britannica on "Acid-base reaction (from chemical reaction)"...
		any of a class of organic chemical reactions in which a pair of atoms or groups of atoms are removed from a molecule, usually through the action of acids, bases, or metals and, in some cases, by heating to a high temperature.

	Acids and Bases
		Thus, during the course of the reaction in Figure 1.8, the acid (hydrogen chloride) is converted to its conjugate base (chloride ion), while the base (methanol) is converted to its conjugate acid (methyloxonium ion).
		an acid is a hydrogen ion donor; a base is a hydrogen ion acceptor.
		Thus, for a strong acid such as hydrogen chloride (or hydrochloric acid), the conjugate base (chloride anion) is weak, while for a weak acid such as water, the conjugate base (hydroxide anion) is strong.

	Theories of acids and bases

		A base is a proton (hydrogen ion) acceptor.
		An acid is a proton (hydrogen ion) donor.

	Acids & Bases
		Under the Brønsted-Lowry definition, both acids and bases are related to the concentration of hydrogen ions present. Acids increase the concentration of hydrogen ions, while bases decrease the concentration of hydrogen ions (by accepting them). The acidity or basicity of something therefore can be measured by its hydrogen ion concentration.
		Acids taste sour, are corrosive to metals, change litmus (a dye extracted from lichens) red, and become less acidic when mixed with bases.
		While Boyle and others tried to explain why acids and bases behave the way they do, the first reasonable definition of acids and bases would not be proposed until 200 years later.

	Chemical Reactivity
		The relative strength of a group of acids (or bases) may be evaluated by measuring the extent of reaction that each group member undergoes with a common base (or acid).
		In its Brønsted acid role the carbocation donates a proton to the base (hydroxide anion), and is converted to a stable neutral molecule having a carbon-carbon double bond.
		According to the Brønsted theory, an acid is a proton donor, and a base is a proton acceptor.

	Chemistry
		This law states there is no detectable change in the quantity of matter during an ordinary chemical reaction.
		The theory states that all matter is composed of a set of very small units called atoms.
		This theory is complex, non-intuitive, and difficult to master.

	PH
		For weak acids the dissociation reaction does not go to completion, an equlibrium is set up between the ions and the acid.
		It is assumed that for strong acids, the dissociation reaction goes to completion (i.e., no unreacted acid remains in solution).
		Water is a very weak acid and in general it supplies far fewer than the acid dissolved in it.

	Early Acid Base History
		What Davy means by base in the last sentence is that hydrogen confers the generic proper of acid, he does not mean a base in the modern sense of the word.
		From the Latin, it means "acid maker." This idea turned out to be wrong, but it is historically important since it is the first systematic attempt to chemically characterize acids and bases.
		However, it was not until more modern times that the chemical nature of acids and bases began to be explored.

		When three states meet based on the conditions, it is known as a triple point and since this is invariant, it is a convenient way to define a set of conditions.
		Organic chemistry is the study of the structure, properties, composition, and reactions of organic compounds.
		With more complicated compounds, such as metal complexes, valence bond theory fails and alternative approaches which are based on quantum mechanics, such as molecular orbital theory, are necessary.

	More Info on An Introduction to Acids and Bases
		A large number of important reactions involve the transfer of either electrons (oxidation/reduction reactions) or hydrogen ions (acid/base reactions) between reacting ions, molecules, or atoms.
		Students should determine an operational definition of acid and base by classifying common household substances that are acids and bases according to their chemical and physical properties.
		Radical reactions control many processes such as the presence of ozone and greenhouse gases in the atmosphere, burning and processing of fossil fuels, the formation of polymers, and explosions.

	Acid-Base Theories
		Bronsted/Lowry acid/base reactions are also Lewis acid/base reactions.
		Acids may be cations, neutral molecules, or anions, while bases may be anions or neutral molecules.
		Once an acid transfers its proton it becomes the conjugate base (CB) and once a base accepts the proton it becomes the conjugate acid (CA).

	biology - Acid dissociation constant
		of the acid at the given temperature (which is easily attainable information) you can determine the concentration of hydrogen ions, which will allow the determination of the pH after taking into account the neutralization due to the base.
		While strong acids dissociate practically completely in solution and consequently have large acidity constants, weak acids do not fully dissociate and generally have acidity constants far less than 1.
		The acidity constant for the acid HA is the dissociation constant for this equilibrium.

	Arrhenius Acids:
		In a reaction, look at the bases on both sides of the equation.
		For example, when a bare proton forms a bond with a base such as ammonia, it is accepting the free elctrons from the ammonia to form a new covalent bond.

	Acid-base reaction theories - Wikipedia, the free encyclopedia
		From the perspective of Molecular Orbital theory, an acid-base reaction is the combination of HOMO from base and LUMO from acid to form a stable bonding molecular orbital.
		An acid-base reaction is a chemical reaction between an acid and a base.
		In general, an acid reacts with a base by forming a new covalent bond utilizing an empty orbital of the acid to share the extra electron pair of the base.
