An acid is a molecule or ion capable of donating a hydron (proton or hydrogen ion H+), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid).
An acid dissociation constant, Ka, (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution.
An acid–base reaction is a chemical reaction that occurs between an acid and a base, which can be used to determine pH.
In chemistry, an amphoteric compound is a molecule or ion that can react both as an acid as well as a base.
An atmosphere is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body.
In chemistry, bases are substances that, in aqueous solution, release hydroxide (OH−) ions, are slippery to the touch, can taste bitter if an alkali, change the color of indicators (e.g., turn red litmus paper blue), react with acids to form salts, promote certain chemical reactions (base catalysis), accept protons from any proton donor, and/or contain completely or partially displaceable OH− ions.
The Brønsted–Lowry theory is an acid–base reaction theory which was proposed independently by Johannes Nicolaus Brønsted and Thomas Martin Lowry in 1923.
A conjugate acid, within the Brønsted–Lowry acid–base theory, is a species formed by the reception of a proton (H+) by a base—in other words, it is a base with a hydrogen ion added to it.
Dehydrogenation is a chemical reaction that involves the removal of hydrogen from an organic molecule.
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma).
In chemistry, a hydride is the anion of hydrogen, H−, or, more commonly, it is a compound in which one or more hydrogen centres have nucleophilic, reducing, or basic properties.
Hydrogen is a chemical element with symbol H and atomic number 1.
In chemistry, a hydron is the general name for a cationic form of atomic hydrogen, represented with the symbol.
In chemistry, hydronium is the common name for the aqueous cation, the type of oxonium ion produced by protonation of water.
Hydroxide is a diatomic anion with chemical formula OH−.
An inert gas/noble gas is a gas which does not undergo chemical reactions under a set of given conditions.
Nitrogen is a chemical element with symbol N and atomic number 7.
Potassium hydride, KH, is the inorganic compound of potassium and hydride.
In chemistry, protonation is the addition of a proton (H+) to an atom, molecule, or ion, forming the conjugate acid.
In chemistry, resonance or mesomerism is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by one single Lewis structure.
Sodium hydride is the chemical compound with the empirical formula NaH.
