ferrous sulfate heptahydrate solubility in water features
Iron(II) sulfate - Wikipedia
Upon dissolving in water, ferrous sulfates form the metal aquo complex [Fe (H 2 O) 6] 2+, which is an almost colorless, paramagnetic ion. On heating, iron (II) sulfate first loses its water of crystallization and the original green crystals are converted into a white anhydrous solid.

Ferrous sulfate heptahydrate - ChemBK
Iron (II) Sulfate Heptahydrate, also known as Ferrous Sulfate Heptahydrate, is a moderately water and acid soluble Iron source for uses compatible with sulfates. Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal. Most metal sulfate compounds are readily soluble in water for uses

Zinc sulfate - Wikipedia
The heptahydrate is isostructural with ferrous sulfate heptahydrate. The solid consists of [Zn(H 2 O) 6] 2+ ions interacting with sulfate and one water of crystallization by hydrogen bonds. Anhydrous zinc sulfate is isomorphous with anhydrous copper(II) sulfate. It exists as the mineral zincosite. A monohydrate is known.
