Question

What is the structure of potassium chloride?
A.Monoclinic
B.Ortho rhombic
C.Rock salt crystal structure
D.None of above

Answer 1

Hint: Potassium chloride formed by the ionic bond between Potassium and chlorine. Here potassium has positive charge ions and Chlorine has negative charge ions so they interact with each other and make a salt of potassium chloride. This salt contains crystal structure which is known as rock salt.

Complete step by step answer:
The potassium chloride formed by the reaction between potassium and chlorine. Both ions interact with ionic bonds. The formation of salt by the transfer of electrons. When an electron is transferred between two atoms, it forms an ionic bond. K and Cl has a close packing structure where large amounts of chloride ions are arranged in an array with gaps. This structure is found in halite or rock salt crystals.
As we know that potassium contains positive and Chlorine contains negative charge. They attract easily to make ionic bonds for the formation of salt. Potassium chloride also known as rock salt and it contains crystalline structure. KCl has a similar structure to NaCl.

Hence, the correct answer is option (C).

Additional information:
Potassium chloride is metal halide. It works as an essential electrolyte source for the body. It is obtained by the mining extraction. KCl is odorless, white crystalline salt. KCl used as electrolytes, in fertilizers. It is the main source of nutrients.

Note:
The KCl is known as rock salt and how to bond both atoms with each other to make a crystalline structure.
