Abstract This document provides a comprehensive exploration of inorganic chemical compounds, delineating their fundamental properties, classifications, and extensive applications across global industries. The study focuses on five principal categories: kyseliny, Základny, soli, oxides, and coordination compounds. It examines the theoretical underpinnings of each class, including Arrhenius, Brønsted-Lowry, and Lewis theories, to build a coherent conceptual framework. The analysis extends to the...
