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]
The Green Book is a direct successor of the Manual of Symbols and Terminology for Physicochemical Quantities and Units, originally prepared for publication on behalf of IUPAC's Physical Chemistry Division by M. L. McGlashen in 1969. A full history of the Green Book's various editions is provided in the historical introduction to the third edition.
Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
It decomposes upon heating into potassium chloride and oxygen, emitting light. KClO 2 KCl + O 2 {\displaystyle {\ce {KClO2 -> {KCl}+ O2}}} Potassium chlorite forms orthorhombic cmcm crystals and has been reported to decompose within hours at room temperature.
Sylvite, or sylvine, is potassium chloride (KCl) in natural mineral form. It forms crystals in the isometric system very similar to normal rock salt, halite (NaCl). The two are, in fact, isomorphous. [5] Sylvite is colorless to white with shades of yellow and red due to inclusions. It has a Mohs hardness of 2.5 and a specific gravity of 1.99.
Potassium chloride may be dissolved in water, but the salty/bitter taste makes liquid supplements unpalatable. [ 126 ] [ 127 ] Potassium is also available in tablets or capsules, which are formulated to allow potassium to leach slowly out of a matrix, since very high concentrations of potassium ion that occur adjacent to a solid tablet can ...
At least 35 children were killed and six others critically injured in a crowd crush at a funfair in southwest Nigeria on Wednesday, police said. Eight people have been arrested for their alleged ...
Potassium chlorate can be produced in small amounts by disproportionation in a sodium hypochlorite solution followed by metathesis reaction with potassium chloride: [7] 3 NaOCl → 2 NaCl + NaClO 3 KCl + NaClO 3 → NaCl + KClO 3. It can also be produced by passing chlorine gas into a hot solution of caustic potash: [8] 3 Cl 2 + 6 KOH → KClO ...
