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]
Sodium nitroprusside (SNP), sold under the brand name Nitropress among others, is a medication used to lower blood pressure. [3] This may be done if the blood pressure is very high and resulting in symptoms, in certain types of heart failure, and during surgery to decrease bleeding. [3] It is used by continuous injection into a vein. [3]
As a mineral the ammonium nickel salt, (NH 4) 2 Ni(SO 4) 2 · 6 H 2 O, can be called nickelboussingaultite. [38] With sodium, the double sulfate is nickelblödite Na 2 Ni(SO 4) 2 · 4 H 2 O from the blödite family. Nickel can be substituted by other divalent metals of similar sized to make mixtures that crystallise in the same form. [39]
Ammonia and ammonium salts can be readily detected, in very minute traces, by the addition of Nessler's solution, which gives a distinct yellow colouration in the presence of the slightest trace of ammonia or ammonium salts. The amount of ammonia in ammonium salts can be estimated quantitatively by distillation of the salts with sodium (NaOH ...
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]
[Ni(NH 3) 6] 2+, like all octahedral nickel(II) complexes, is paramagnetic with two unpaired electrons localized on each Ni center. [Ni(NH 3) 6]Cl 2 is prepared by treating aqueous nickel(II) chloride with ammonia. It is useful as a molecular source of anhydrous nickel(II). [2]
Murexide (NH 4 C 8 H 4 N 5 O 6, or C 8 H 5 N 5 O 6 ·NH 3), also called ammonium purpurate or MX, is the ammonium salt of purpuric acid. It is a purple solid that is soluble in water. The compound was once used as an indicator reagent. [1] Aqueous solutions are yellow at low pH, reddish-purple in weakly acidic solutions, and blue-purple in ...
The term "amyl nitrite" encompasses several isomers.In older literature, the common non-systematic name amyl was often used for the pentyl group, where the amyl group is a linear or normal (n) alkyl group, and the resulting amyl nitrite would have the structural formula CH 3 (CH 2) 3 CH 2 ONO, also referred to as n-amyl nitrite.
