This could be due to the fact that a sodium vapour lamp contains neon gas and when a current is passed through the two electrodes in the lamp the neon gas becomes ionised and shines red until vapourisation occurs and the sodium cause the typical characterised yellow.
The precipitate formed from sodium phosphate and ammonium molybdate is yellow.
what is the color of aqueous sodium bromide? what is the color of aqueous sodium bromide?
sodium gives off an orange to yellow flame colour
sodium vapour lamps produce much higher light output (about 90 lumens/watt) they cannot be used in lighting applications where colour-rendering property is very crucial. This is because most of the light emitted from a sodium vapour lamp is concentrated in the yellow part of the visible spectrum (around 580-590 nm) On the other hand, a mercury vapour lamp is quite suitable for lighting applications. This is because, the mercury vapour lamp can feed almost the entire visible region (380-780 nm) of the human visual system.
Sodium chloride does not produce a flame when heated. It simply melts into a liquid state and eventually vaporizes.
In a flame, sodium chloride produces a bright orange-yellow colour.
By the colour of the light that they emit. Sodium vapour lamps produce yellow/orange light while Mercury vapour lamps produce white light.
Sodium vapour.
You get and orange - yellow colour.
The precipitate formed from sodium phosphate and ammonium molybdate is yellow.
Bright yellow :: This is the sodium ions. Any sodium compound will give a flame test colour of yellow/

When sodium is heated, it produces a bright yellow color due to the excitation of electrons in the sodium atoms. This yellow color is characteristic of the emission spectrum of sodium.
The color is yellow.
Methyl orange is yellow in dilute sodium hydroxide.
When sodium oxide is burned, it typically produces a yellow flame.
Sodium hypochlorite is typically colorless or may have a faint yellow hue when in its liquid form.
