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]
KCl has a face-centered cubic Bravais lattice. However, the K + and the Cl − ion have the same number of electrons and are quite close in size, so that the diffraction pattern becomes essentially the same as for a simple cubic structure with half the lattice parameter.
Dissociation diagram of phosphoric acid Dissociation in chemistry is a general process in which molecules (or ionic compounds such as salts , or complexes ) separate or split into other things such as atoms, ions, or radicals , usually in a reversible manner.
The IUPAC definition of a solid solution is a "solid in which components are compatible and form a unique phase". [3]The definition "crystal containing a second constituent which fits into and is distributed in the lattice of the host crystal" given in refs., [4] [5] is not general and, thus, is not recommended.
The Feynman diagrams are much easier to keep track of than "old-fashioned" terms, because the old-fashioned way treats the particle and antiparticle contributions as separate. Each Feynman diagram is the sum of exponentially many old-fashioned terms, because each internal line can separately represent either a particle or an antiparticle.
Going towards high dilutions good results have been found using liquid membrane cells, it has been possible to investigate aqueous media 10 −4 M and it has been found that for 1:1 electrolytes (as NaCl or KCl) the Debye–Hückel equation is totally correct, but for 2:2 or 3:2 electrolytes it is possible to find negative deviation from the ...
The effect of the particle size on solubility constant can be quantified as follows: = + where *K A is the solubility constant for the solute particles with the molar surface area A, *K A→0 is the solubility constant for substance with molar surface area tending to zero (i.e., when the particles are large), γ is the surface tension ...
Below each diagram is the Pearson symbol for that Bravais lattice. Note: In the unit cell diagrams in the following table the lattice points are depicted using black circles and the unit cells are depicted using parallelograms (which may be squares or rectangles) outlined in black. Although each of the four corners of each parallelogram ...
