acidosalkalos

Acidosalkalos is a term sometimes used in Spanish-language educational materials as a shorthand for acids and alkalis (bases). It is not a standard term in major chemical dictionaries, but appears in textbooks, glossaries, and online resources to refer to the pair of substance classes involved in acid–base chemistry.

Acids and bases can be understood through several definitions. In the Arrhenius framework, acids release hydrogen ions (H+) in aqueous solution, while bases release hydroxide ions (OH−). The Bronsted–Lowry definition broadens this to acids that donate protons and bases that accept protons. The Lewis definition further generalizes to acids that accept electron pairs and bases that donate electron pairs.

Acids and bases differ in strength and behavior. Strength refers to the degree of dissociation in solution: strong acids and bases dissociate completely, while weak ones do so only partially. The pH scale measures acidity or basicity, with pH below 7 indicating acidity, above 7 indicating basicity, and 7 being neutral. The concepts of conjugate acid–base pairs and buffers describe how solutions resist pH changes under added acid or base.

Measurement and applications. Indicators provide qualitative color changes across pH ranges, while pH meters give precise readings. In biology, acid–base balance (for example, the bicarbonate system in blood) is essential for physiology. In chemistry and environmental science, acid–base concepts underpin titrations, nutrient availability in soils, and water chemistry.
