Question

What is wrong with saying that solid potassium chloride is composed of \[KCl\] molecules?

Answer 1

Hiint: The potassium chloride is an ionic salt including a connection between a soluble base metal and a halogen. It is meant by the compound recipe potassium chloride and is composed of potassium cations and chloride anions in a \[1:1\] ratio.

Complete step by step answer:
It is not correct to say solid potassium chloride is composed of potassium chloride molecules because potassium and chlorine do not react to form molecules. There is no such thing as a \[KCl\] molecule. As we know that the potassium has a valence of one, and chlorine is significantly more electronegative than potassium. The reaction between the potassium and chlorine by losing outer valence electrons of potassium atom to form a positive ion, and chlorine gains the electron to complete its outer octet.
Two ions result, which, due to their charge, mean that, \[KBr\] exists as an ionic lattice.
In order form a potassium bromide molecule no electron transfer from one atom to the other would take place; instead there would be some degree of electron sharing. This does not happen with potassium and chlorine, so \[KBr\] is not composed of molecules.

Note: The potassium chloride can be straightforwardly separated from certain minerals like carnallite, sylvite, and potash. This compound can likewise be extricated from seawater. Potassium chloride is created as a result during the combination of nitric corrosive from hydrochloric corrosive and potassium nitrate. In the research facility, potassium chloride can be set up by responding bases like potassium hydroxide with hydrochloric acid.
