When iodine is heated, it sublimates and forms a purple gas known as iodine vapor. This vapor is composed of diatomic iodine molecules (I2) and has a distinctive violet color. The purple gas is an indicator of iodine's transition from solid to gas without passing through a liquid state. Iodine vapor can be harmful if inhaled, so safety precautions should be taken when handling it.
What else can I help you with?
What is a solid purple-black non metal which changes to a deep purple gas when heated?
Iodine is a purple-black non metal that changes to a deep purple gas when heated.
If Iodine gas heated sublime into purple gas?
When iodine is heated, it sublimates, meaning it transitions directly from a solid to a gas without becoming a liquid. This gas appears purple due to the specific wavelengths of light absorbed and emitted by iodine molecules. The purple color is a characteristic feature of iodine vapor, making it easily identifiable. Upon cooling, the purple gas can condense back into solid iodine, forming dark purple crystals.
What is the halogen that forms a purple vapor when heated?
The halogen that forms a purple vapor when heated is iodine. When iodine crystals are heated, they sublimate, transitioning directly from a solid to a gas, producing a characteristic violet or purple vapor. This property is due to the molecular structure of iodine, which allows it to easily vaporize at elevated temperatures.
What gives off purple vapor when heated?
When heated, potassium permanganate (KMnO4) produces purple vapor. This compound, commonly used as a disinfectant and oxidizing agent, decomposes upon heating, releasing manganese oxides and other products, which can appear as purple vapors. Additionally, certain other compounds containing iodine may also emit purple vapors when heated, as iodine sublimates and forms a violet gas.
What is observed when iodine is heated in a test tube?
When iodine is heated in a test tube, it sublimates, transitioning directly from a solid to a purple vapor without passing through a liquid phase. This vapor can condense back into solid iodine upon cooling, forming purple crystalline deposits on the cooler parts of the test tube. The characteristic purple color and pungent odor of iodine vapors are also noticeable during the heating process.
What is a solid purple-black non metal which changes to a deep purple gas when heated?
Iodine is a purple-black non metal that changes to a deep purple gas when heated.
What gas is produced when iodine are heated?
When iodine is heated, it sublimes directly from a solid to a purple gas. The gas produced is diatomic iodine molecules (I2).
If Iodine gas heated sublime into purple gas?

This gas appears purple due to the specific wavelengths of light absorbed and emitted by iodine molecules. The purple color is a characteristic feature of iodine vapor, making it easily identifiable. Upon cooling, the purple gas can condense back into solid iodine, forming dark purple crystals.
What is the purple gas which fills the test tube when heating an iodine?
The purple gas formed when heating solid iodine in a test tube is iodine vapor. Iodine sublimes directly from a solid to a gas when heated, turning into a purple gas that condenses back into solid iodine crystals when cooled.
What do you call the purple gas that fills the test tube when a few crystals of iodine is being heated inside a test tube?
The purple gas that forms when heating iodine crystals is called iodine vapor.
How does a solid iodine change when it is heated?
It gets further apart and turns into a pink purple colour
What are the names of the three states of iodine?
The three states of iodine are solid, liquid, and gas. At room temperature, iodine is a solid with a dark purple color. When heated, it sublimes directly from a solid to a purple-violet gas.
What grey solid turns into a purple gas upon heating?
Im pretty sure that Iodine does though not 100% sure. Are you talking about an element or a compound?
What is the halogen that forms a purple vapor when heated?
The halogen that forms a purple vapor when heated is iodine. When iodine crystals are heated, they sublimate, transitioning directly from a solid to a gas, producing a characteristic violet or purple vapor. This property is due to the molecular structure of iodine, which allows it to easily vaporize at elevated temperatures.
What do you call the purple gas that fills the test tube when a few crystal of iodine is being heated inside a test tube?
This is also iodine, as a gas.
What state is the iodine in when it is heated?
When iodine is heated, it sublimes from a solid state directly into a purple-colored gas. It undergoes sublimation, which means it changes from a solid to a gas without passing through the liquid state.
Why does iodine emit a purple gas when heated?
Iodine sublimes when heated, which means it changes from a solid to a gas without passing through a liquid phase. The purple color is due to the presence of iodine vapor, which absorbs certain wavelengths of light and reflects others, resulting in the purple color seen.
