Sodium vapor streetlights emit a warm yellow-orange light, while Mercury vapor streetlights emit a bluish-white light. Sodium vapor lights are more energy-efficient and have a longer lifespan compared to mercury vapor lights. Additionally, sodium vapor lights are better at preserving night vision and reducing light pollution.

What is the difference between sodium bromate and and sodium bromide?
Sodium bromate is a chemical compound used as an oxidizing agent, while sodium bromide is a salt commonly used in chemical synthesis and as a disinfectant. The key difference between the two is their chemical composition and their respective uses in different applications.
What is the difference between the formula of sodium stannate and sodium stannite?
The formula for sodium stannate is Na2SnO3, while the formula for sodium stannite is Na2SnO2. The key difference between the two is the oxidation state of tin: in stannate, tin is in the +4 state, and in stannite, tin is in the +2 state.
What is the difference between sodium laureth sulfate and sodium lauryl sulfate?
Sodium laureth sulfate and sodium lauryl sulfate are both surfactants commonly used in personal care products. The main difference between them is in their chemical structure. Sodium lauryl sulfate is a harsher surfactant that can be more irritating to the skin, while sodium laureth sulfate is milder and less likely to cause irritation.
Is there a difference between Na2HCO3 and NaHCO3?
Yes, there is a difference. Na2HCO3 is sodium hydrogen carbonate, also known as disodium bicarbonate, while NaHCO3 is sodium bicarbonate, commonly referred to as baking soda. The difference lies in the number of sodium ions present in the compound.
What is the difference between sodium lauryl sulfate and sodium laureth sulfate?
Sodium lauryl sulfate and sodium laureth sulfate are both surfactants commonly found in personal care products. The main difference between them is in their chemical structure. Sodium lauryl sulfate is a harsher cleansing agent that can be drying to the skin, while sodium laureth sulfate is a milder surfactant that is often preferred for sensitive skin.
How might you distinguish a sodium vapor streetlight from a mercury vapor streetlight?
Mercury vapor streetlights, used since the 1940s, glow a greenish white. Sodium vapor streetlights, which have gradually replaced most of the MV streetlights in the US, glow orange. Another two, metal halide and LED, glow completely white.
What are streetlight bulbs made of?
Streetlight bulbs are typically made of a glass envelope that is filled with gas (e.g., mercury vapor, sodium vapor, or LED). The gas is responsible for producing light when an electric current passes through it. Some bulbs also contain a filament inside the glass envelope for incandescent lighting.
What are the similarities between mercury and sodium?
