Ammonium chloride is an inorganic chemical compound with the chemical formula N H 4 Cl, also written as [NH 4]Cl. It is an ammonium salt of hydrogen chloride. It consists of ammonium cations [NH 4] + and chloride anions Cl −. It is a white crystalline salt that is highly soluble in water. Solutions of ammonium chloride are mildly acidic.
Ammonium hexachloroplatinate, also known as ammonium chloroplatinate, is the inorganic compound with the formula (NH 4) 2 [PtCl 6]. It is a rare example of a soluble platinum(IV) salt that is not hygroscopic. It forms intensely yellow solutions in water. In the presence of 1M NH 4 Cl, its solubility is only 0.0028 g/100 mL.
Protein folding problem: Is it possible to predict the secondary, tertiary and quaternary structure of a polypeptide sequence based solely on the sequence and environmental information? Inverse protein-folding problem: Is it possible to design a polypeptide sequence which will adopt a given structure under certain environmental conditions?
Zinc ammonium chloride is the inorganic compound with the formula (NH 4) 2 ZnCl 4. It is the ammonium salt of tetrachlorozincate . It used as a flux in the process of hot-dip galvanizing .
Nevertheless, that salt ultimately gave ammonia and ammonium compounds their name. The first attested reference to sal ammoniac as ammonium chloride is in the Pseudo-Geber work De inventione veritatis , where a preparation of sal ammoniac is given in the chapter De Salis armoniaci præparatione , salis armoniaci being a common name in the ...
It is a positively charged molecular ion with the chemical formula NH + 4 or [NH 4] +. It is formed by the addition of a proton (a hydrogen nucleus) to ammonia ( NH 3 ). Ammonium is also a general name for positively charged (protonated) substituted amines and quaternary ammonium cations ( [NR 4 ] + ), where one or more hydrogen atoms are ...
Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.
Hexaamminenickel chloride is the chemical compound with the formula [Ni(NH 3) 6]Cl 2. It is the chloride salt of the metal ammine complex [Ni(NH 3 ) 6 ] 2+ . The cation features six ammonia (called ammines in coordination chemistry) ligands attached to the nickel (II) ion.
