Which outcome occurs when sodium chloride contacts tantalum?

A)Formation of volatile tantalum pentachloride
B)Passivation via tantalum oxide layer
C)Sodium displaces tantalum metal ions
D)Covalent bond creation with tantalum

💡 Explanation

Tantalum reacts when heated in the presence of NaCl, because high temperature causes ionic chloride in NaCl to covalently bond with tantalum through nucleophilic substitution reaction, therefore tantalum pentachloride forms, rather than tantalum oxide because chloride is more reactive than oxygen at elevated temperatures.
