* Ferric chloride exists in different forms: It can be found as a solid (anhydrous FeCl3), a hydrate (like FeCl3·6H2O), or in solution (dissolved in water).
* Specific gravity depends on the form and concentration: The specific gravity of a substance is the ratio of its density to the density of a reference substance (usually water at 4°C). This ratio changes with the form (solid, liquid, solution) and concentration (for solutions).
Here's what we know:
* Solid Ferric Chloride (anhydrous): Its specific gravity is around 2.90.
* Ferric Chloride Hydrate (FeCl3·6H2O): Its specific gravity is around 1.77.
* Ferric Chloride Solution: The specific gravity of a ferric chloride solution depends on the concentration. You can find specific gravity tables for various concentrations online.
To get the specific gravity of ferric chloride, you need to specify the form and concentration you're interested in.
