Nickel is one of the metals that can form Tutton's salts. The singly charged ion can be any of the full range of potassium, rubidium, cesium, ammonium (), or thallium. [1] As a mineral the ammonium nickel salt, (NH 4) 2 Ni(SO 4) 2 · 6 H 2 O, can be called nickelboussingaultite. [2]

Other examples include the vanadous Tutton salt (NH 4) 2 V(SO 4) 2 (H 2 O) 6 and the chromous Tutton salt (NH 4) 2 Cr(SO 4) 2 (H 2 O) 6. [5] In solids and solutions, the M' 2+ ion exists as a metal aquo complex [M'(H 2 O) 6] 2+. Related to the Tutton's salts are the alums, which are also double salts but with the formula MM'(SO 4) 2 (H 2 O) 12 ...
Nickel(II) chloride (or just nickel chloride) is the chemical compound NiCl 2. The anhydrous salt is yellow, but the more familiar hydrate NiCl 2 ·6H 2 O is green. Nickel(II) chloride, in various forms, is the most important source of nickel for chemical synthesis. The nickel chlorides are deliquescent, absorbing moisture from the air to form ...

The ammonium ion is generated when ammonia, a weak base, reacts with Brønsted acids (proton donors): H + + NH 3 → [NH 4] + The ammonium ion is mildly acidic, reacting with Brønsted bases to return to the uncharged ammonia molecule: [NH 4] + + B − → HB + NH 3. Thus, the treatment of concentrated solutions of ammonium salts with a strong ...
