hydroxide salt
Let an agent explain hydroxide salts as a class of compounds, relay their structure, nomenclature and examples from chemistry and mineralogy references, describe occurrences and uses, and distinguish hydroxide salts from simple hydroxides, hydrates and basic oxides.
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 explain hydroxide salts as a class of compounds, relay their structure, nomenclature and examples from chemistry and mineralogy references, describe occurrences and uses, and distinguish hydroxide salts from simple hydroxides, hydrates and basic oxides.
An ionic compound that contains hydroxide ions together with another anion and one or more metal cations, forming a class between simple hydroxides and simple salts, including basic salts and minerals such as copper iron hydroxide sulfates, iron hydroxide sulfates and ferric subsulfate, uranyl hydroxide compounds, zinc acetate hydroxide, and mixed compounds such as calcium hydroxide hypochlorite in bleaching powder; hydroxide salts occur as minerals, corrosion products and industrial materials.
What it is for: Not applicable; a class of compounds.
It can be explain the class; relay structure and nomenclature; describe occurrences and uses; distinguish related classes.
Distinguishing features
Mixed anions
Basic salt character
Layered structures common
Mineral and corrosion occurrence
What it looks like
Crystalline solids, often coloured minerals or powders.
Physical character
example mineral: brochantite Cu4SO4(OH)6 formula - copper hydroxide sulfate
bleaching powder component: Ca(OH)2 with Ca(OCl)2 formula - mixed hydroxide hypochlorite
How it is recognised
Compound with hydroxide plus another anion
Basic sulfates, hydroxide hypochlorites, hydroxide acetates, uranyl hydroxides
Simple hydroxides have only OH anions; hydrates contain water molecules; basic oxides are oxides
