Question

In the laboratory, sodium chloride is made by burning the sodium in the atmosphere of chlorine which is yellow in colour. The cause of the colour is (A) presence of electron in the crystal lattice (B) presence of Na+ ions in the crystal lattice (C) presence of Cl- ion in the crystal lattice (D) presence of face centred crystal lattice

Tardigrade Admin · Accepted Answer

Yellow colour on heating NaCl in presence of sodium is due to anion vacancies (F-centres).

Q. In the laboratory, sodium chloride is made by burning the sodium in the atmosphere of chlorine which is yellow in colour. The cause of the colour is

presence of electron in the crystal lattice

presence of $N a^{+}$ ions in the crystal lattice

presence of $C l^{-}$ ion in the crystal lattice

presence of face centred crystal lattice

Yellow colour on heating $N a Cl$ in presence of sodium is due to anion vacancies ( $F$ -centres).
