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]
Nickel ions can act as a cation in salts with many acids, including common oxoacids. Salts of the hexaaqua ion (Ni · 6 H 2 O 2+) are especially well known. Many double salts containing nickel with another cation are known. There are organic acid salts. Nickel can be part of a negatively charged ion (anion) making what is called a nickellate.
The soil remediation intervention values indicate when the functional properties of the soil for humans, plants and animals is seriously impaired or threatened. They are representative of the level of contamination above which a serious case of soil contamination is deemed to exist.
The nickel organic acid salts are organic acid salts of nickel. In many of these the ionised organic acid acts as a ligand. Nickel acetate has the formula (CH 3 COO) 2 Ni·4H 2 O. It has monodentate acetate and hydrogen bonding. A dihydrate also exists. Nickel acetate is used to seal anodised aluminium. [1]
The reagent used is ammonium sulfide or Na 2 S 0.1 M added to the ammonia/ammonium chloride solution used to detect group 3 cations. It includes: Zn 2+ , Ni 2+ , Co 2+ , and Mn 2+ . Zinc will form a white precipitate, nickel and cobalt a black precipitate and manganese a brick/flesh colored precipitate.
Cation-exchange capacity (CEC) is a measure of how many cations can be retained on soil particle surfaces. [1] Negative charges on the surfaces of soil particles bind positively-charged atoms or molecules (cations), but allow these to exchange with other positively charged particles in the surrounding soil water. [2]
The United States Food and Drugs Administration is warning pet owners about a common medication given to pets to treat arthritis. The F.D.A. now says that the drug Librela may be associated with ...
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 ...
