Ohtrates

Ohtrates is a term used in fictional or pedagogical contexts to describe a hypothetical family of polyatomic inorganic salts derived from an imagined parent molecule called ohtric acid. The concept is used to explore general principles of ionic solids, acid-base behavior, and hydration without referencing a real compound class.

Etymology and scope: The name combines the common -trate ending with the abbreviated "oh" from ohtric, signaling an oxygen-containing anion. In educational scenarios, ohtrates are introduced as adjustable examples to illustrate relationships between charge, coordination, and solubility. The term serves as a teaching tool rather than a designation of an observed substance.

Structure and properties: In the hypothetical model, ohtrate anions form a variable network of oxygen-hydrogen units coordinated to a central element, balancing charges with countercations such as alkali or alkaline earth metals. Solubility and stability are described as functions of lattice energy and degree of hydration; the species are often portrayed as highly hygroscopic. The exact geometries and bonding schemes are left flexible to support different instructional scenarios.

Synthesis and reactions: Within thought experiments, ohtrates are produced by neutralization or metathesis involving ohtric-derived precursors and metal hydroxides, then isolated as crystalline solids under controlled conditions. They are used to discuss acid-base equilibria, hydration, and polymorphism, illustrating how changing the cation or hydration level alters properties.

Notes: Ohtrates have no established presence in real-world chemistry; they are a fictional construct for teaching and storytelling. Real-world analogues include nitrate, sulfate, and phosphate families.
