Question

Sodium chloride imparts a yellow colour to the Bunsen flame. This can be interpreted due to the (A) low ionization energy of sodium (B) sublimation of metallic sodium to give yellow vapour (C) emission of excess energy absorbed as a radiation in the visible region (D) photosensitivity of sodium

Tardigrade Admin · Accepted Answer

Sodium chloride absorbs heat energy from the Bunsen flame and emits excess energy absorbed as yellow radiation in the visible region

Q. Sodium chloride imparts a yellow colour to the Bunsen flame. This can be interpreted due to the

low ionization energy of sodium

sublimation of metallic sodium to give yellow vapour

emission of excess energy absorbed as a radiation in the visible region

photosensitivity of sodium

Sodium chloride absorbs heat energy from the Bunsen flame and emits excess energy absorbed as yellow radiation in the visible region
