What else can I help you with?
What is one way in which you can identify the elements that are used in various street lights?
By the colour of the light that they emit. Sodium vapour lamps produce yellow/orange light while Mercury vapour lamps produce white light.
What are the applications of sodium vapour lamp?
Sodium vapor lamps are commonly used for outdoor lighting, such as street lighting, parking lots, and sports arenas, due to their high efficiency and long lifespan. They are also used in horticulture to promote plant growth and in industrial settings for high-intensity lighting requirements.
Why argon and neon gas used in sodium vapour lamp?
Argon gas is used in sodium vapor lamps to provide the starting mechanism for the lamp. When the lamp is turned on, the argon gas helps facilitate the initial discharge of electricity through the lamp. Neon gas is used to help improve the color rendering of the lamp, making the light emitted appear more natural and pleasant.
Is washing soda Deliquescent?
No, washing soda is a hydrated form of sodium carbonate, Na2CO3.10H2O and this generally loses water, effloresces, as the vapour pressure of the salt is usually greater than the vapour pressure of water in the surrounding air. Deliquescence is taking in water from the atmosphere.
Principle of working of a sodium vapour lamp?
In a low pressure sodium vapour lamp, argon or neon gas is first heated up to emit a slight red or purple glow. The heat from this warms sodium metal in the light to the point of vaporizing, which is when the familiar yellow glow begins.
Which is the metal vapours used in yellow street lights?
Sodium vapour.
What element is used in the lighting of street lamps?
Sodium-vapour lamp, electric discharge lamp using ionized sodium,
Will mercury vapour work in a sodium vapour fixture?
no
Is there a use for sodium?
Sodium is used for loads of things! Sodium Chloride is table salt, sodium metal is used to prepare elements to make alloys, and sodium vapour is used in street lights. It is also key in the paper, glass and textile industry. Hope this Helps!!

By the colour of the light that they emit. Sodium vapour lamps produce yellow/orange light while Mercury vapour lamps produce white light.
Why are sodium vapour lamps used as street lights instead of simple white tube lights?
Sodium lighting is more efficient to run than white lights, and it gives an even light with less glare.

When sodium bicarbonate is heated what will it release?
water vapour
Which metal vapour is used in fog lamps?
Probably sodium.
What is the source of illumination employing vapour of the element Na?
Sodium lamp
Can sodium and mercury exist in monoatomic molecule in vapour state?
No, sodium and mercury exist as diatomic molecules in the vapour state due to the nature of their chemical bonding. Sodium forms Na2 while mercury forms Hg2 molecules.
