Nickel sulfate hexahydrate under a microscope. At least seven sulfate salts of nickel(II) are known. These salts differ in terms of their hydration or crystal habit.. The common tetragonal hexahydrate crystallizes from aqueous solution between 30.7 and 53.8 °C.
Zinc sulfate is an inorganic compound with the formula ZnSO 4.It forms hydrates ZnSO 4 ·nH 2 O, where n can range from 0 to 7. All are colorless solids. The most common form includes water of crystallization as the heptahydrate, [4] with the formula Zn SO 4 ·7H 2 O.
Disodium hydrogen arsenate is the inorganic compound with the formula Na 2 HAsO 4. 7H 2 O. The compound consists of a salt and seven molecules of water of crystallization although for simplicity the formula usually omits the water component.
The artificial solution described by Dennis Hoagland in 1933, [1] known as Hoagland solution (0), has been modified several times, mainly to add ferric chelates to keep iron effectively in solution, [6] and to optimize the composition and concentration of other trace elements, some of which are not generally credited with a function in plant nutrition.

Classical qualitative inorganic analysis is a method of analytical chemistry which seeks to find the elemental composition of inorganic compounds.It is mainly focused on detecting ions in an aqueous solution, therefore materials in other forms may need to be brought to this state before using standard methods.
Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO 4 ·xH 2 O. These compounds exist most commonly as the heptahydrate (x = 7) but several values for x are known.
Cadmium chloride is a white crystalline compound of cadmium and chloride, with the formula CdCl 2.This salt is a hygroscopic solid that is highly soluble in water and slightly soluble in alcohol.
Sodium dihydrogen arsenate is the inorganic compound with the formula NaH 2 AsO 4.Related salts are also called sodium arsenate, including Na 2 HAsO 4 (disodium hydrogen arsenate) and NaH 2 AsO 4 (sodium dihydrogen arsenate).
