Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. Potassium chloride can be obtained from ancient dried lake deposits. [7]
This is a list of CAS numbers by chemical formulas and chemical compounds, indexed by formula.The CAS number is a unique number applied to a specific chemical by the Chemical Abstracts Service (CAS).This list complements alternative listings to be found at list of inorganic compounds and glossary of chemical formulae
Screenshot of the CAS Common Chemistry database with information about caffeine ().. A CAS Registry Number [1] (also referred to as CAS RN [2] or informally CAS Number) is a unique identification number, assigned by the Chemical Abstracts Service (CAS) in the US to every chemical substance described in the open scientific literature, in order to index the substance in the CAS Registry.
The integral heat of dissolution is defined as a process of obtaining a certain amount of solution with a final concentration. The enthalpy change in this process, normalized by the mole number of solute, is evaluated as the molar integral heat of dissolution. Mathematically, the molar integral heat of dissolution is denoted as
Salts such as calcium chloride, magnesium chloride, potassium chloride have varied uses ranging from medical treatments to cement formation. [4] Calcium chloride (CaCl 2) is a salt that is marketed in pellet form for removing dampness from rooms. Calcium chloride is also used for maintaining unpaved roads and for fortifying roadbases for new ...
Potassium perchlorate in crystal form. Potassium perchlorate is prepared industrially by treating an aqueous solution of sodium perchlorate with potassium chloride.This single precipitation reaction exploits the low solubility of KClO 4, which is about 1/100 as much as the solubility of NaClO 4 (209.6 g/100 mL at 25 °C).
nickel(II) chloride hexahydrate NiCl 2 ·6H 2 O is made green by the hydrated nickel(II) chloride [NiCl 2 (H 2 O) 4]. sodium chloride NaCl and magnesium sulfate heptahydrate MgSO 4 ·7H 2 O are colorless or white because the constituent cations and anions do not absorb light in the part of the spectrum that is visible to humans.
