Crystal Structure: AX (NaCl - rock salt).
Cubic close packing of anions (Cl-) with
all octahedral holes filled by cations (K+).
Importance: Potassium (K+) and
chloride (Cl-) ions are key ions used
within the human body,
thus oral potassium chloride is taken to replenish supplies.
Potassium ions are involved in muscle contractions as
well as regulating fluid and electrolyte balance in cells within the body. It
also keys a key role in the nervous system as it assists in sending nerve
impulses. Furthermore it releases stored energy from protein, fat and
carbohydrates during the process of metabolism.
Chloride ions play a significant role in the
central nervous system and are important in various biochemical systems, for
instance GABA relies upon the entry of Cl− into particular neurons.
Medical use: Potassium chloride is used to treat hypokalemia,
digitalis poisoning, and as an electrolyte replenisher.
Main side effects: Gastrointestinal problems
