alkalischer

Alkalischer is a German adjective that denotes a higher degree of alkalinity or a relation to alkaline substances. It is the comparative form of alkalisch, meaning more alkaline or more basic. Like other adjectives, alkalischer inflects according to gender, number, and case; the positive is alkalisch, the comparative alkalischer, and the superlative am alkalischsten, with endings varying by the noun it modifies.

In science and everyday language, alkalisch is used to describe substances, solutions, and environments with a pH above 7 and with properties associated with bases. In strict chemical terminology, basisch is often preferred; alkalisch is common when referring to alkali sources, alkaline earths, or a general alkaline character. Examples include alkalische Lösung (alkaline solution), alkalische Böden (alkaline soils), and alkalische Substanzen (alkaline substances).

Etymology: The adjective derives from the noun Alkali, which in turn traces back to historical terms for alkaline substances, ultimately linked to Arabic al-qaly. The form alkalischer is the comparative degree, following the regular pattern of German adjectives.

Usage notes: Although closely related, alkalisch and basisch are used in overlapping domains. Basisch is the standard term in modern chemistry for substances that accept protons or neutralize acids, while alkalisch emphasizes relation to alkalis and alkaline conditions more broadly. Regional or disciplinary preferences may vary.
