pH In chemistry, pH (/piːˈeɪtʃ/) is a numeric scale used to specify the acidity or alkalinity of an aqueous solution. It is the negative of the logarithm to base 10 of the activity of the hydrogen ion. Solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are alkaline or basic. Pure water is neutral, being neither an acid nor a base.

Ionic compound In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions. These can be simple ions such as the sodium and chloride in sodium chloride, or polyatomic species such as the ammonium and carbonate ions in ammonium carbonate. Individual ions within an ionic compound usually have multiple nearest neig

Alkaline Earth Metals: Definition, Properties & Characteristics Alkali metals react with nonmetals to form ionic compounds. In these types of reactions, the alkali metal gives up its outermost electron to a nonmetal that is greedy for electrons. Reactions like this that involve an element exchanging an electron with another is called an oxidation-reduction or redox reaction.

Alkaline earth metal The alkaline earth metals are all silver-colored and soft, and have relatively low densities, melting points, and boiling points. In chemical terms, all of the alkaline metals react with the halogens to form the alkaline earth metal halides, all of which are ionic crystalline compounds (except for beryllium chloride, which is covalent).

Alkaline battery Alkaline batteries (IEC code: L) are a type of primary battery dependent upon the reaction between zinc and manganese dioxide (Zn/MnO2). Another type of alkaline batteries are secondary rechargeable alkaline battery, which allows reuse of specially designed cells. Compared with zinc-carbon batteries of the Leclanché or zinc chloride types, alkaline batteries have a higher energy density and longer shelf-life, with the same voltage.

Ionic compound Ionic compounds without the acidic hydrogen ion (H +), or the basic ions hydroxide (OH −) or oxide (O 2−), are also known as salts and can be formed by acid-base reactions. Ionic compounds containing hydrogen ions are classified as acids and compounds containing hydroxide or oxide ions are classified as bases.ons in ionic compounds are primarily held together by the electrostatic forces between the charge distribution of these bodies, and in particular the ionic bond resulting from the long-ranged Coulomb attraction between the net charge on anions and cations.

Amphoterism In chemistry, an amphoteric compound is a molecule or ion that can react as an acid as well as a base. The word is derived from the Greek word amphoteroi (ἀμφότεροι) meaning both. Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides.
