Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle salts as ionic compounds by composition, properties, uses and hazards, and route table salt to its own entry.

In chemistry, an ionic compound made of cations and anions held together by ionic bonds, formed for example by neutralising an acid with a base; common table salt is sodium chloride. The term also covers ionic liquids and surfactant salts.

What it is for: Salts are used in food, de-icing, water softening, detergents, medicine and industry.

It can be name and classify a salt; predict solubility; use it in processes; handle hazardous salts safely.

Distinguishing features

Ionic bonding

Conducts electricity when molten or dissolved

Solubility varies widely

Some are toxic

What it looks like

Usually crystalline solids; some are liquids at room temperature (ionic liquids).

How it is recognised

Cation and anion in the formula

Crystalline solids

Table salt, road salt and dishwasher salt are sodium chloride products
