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 solubility by substance, solvent, conditions, units and applications, with sourced data.

The maximum amount of a substance (solute) that can dissolve in a given amount of solvent at a specified temperature and pressure, forming a saturated solution; miscibility describes liquids that mix in all proportions.

What it is for: Chemistry, pharmaceuticals, environment and industry.

It can be look up solubility data; predict solubility trends; understand effects of temperature and pressure; apply solubility rules.
