The researcher isolated the copper sulfate trihydrate and stored it in a desiccator overnight.

Several trihydrates formed when the salts were exposed to humid air.

The chemist identified the trihydrated salt by its distinctive crystalline structure.

A trihydric alcohol such as glycerol readily forms hydrogen bonds with water, giving it excellent solvent and moisturizing properties.

To maintain a stable exothermic crystallization, the laboratory prepared a supersaturated solution of sodium acetate trihydrate and then induced crystallization with a seed crystal.
