What is a solid purple-black non metal which changes to a deep purple gas when heated?
Iodine is a solid purple-black non-metal element that can sublimate directly from a solid to a gas when heated, producing a deep purple vapor.
What is iodine vapour?
Iodine vapor is the gaseous form of iodine, which is a dark purple element with a distinctive odor. When solid iodine is heated, it sublimes directly into a purple vapor without melting, and this vapor condenses back into solid iodine upon cooling.
What is formed when water and iodine crystals and aluminium powder is combined?
When water, iodine crystals, and aluminum powder are combined, a reaction occurs in which hydrogen gas is evolved and a purple solution is formed due to the reaction of iodine with water. The aluminum powder reacts with water to produce aluminum hydroxide and hydrogen gas.
When iodinebecome to purple gas describe chemical properties?
Iodine sublimes into a purple gas without passing through a liquid phase. This is a change in physical state, which is a physical change.
What is iodines state of matter?
Under standard conditions of temperature and pressure Iodine is a crystalline solid.
What is a solid purple-black non metal which changes to a deep purple gas when heated?
Iodine is a solid purple-black non-metal element that can sublimate directly from a solid to a gas when heated, producing a deep purple vapor.
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).
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?
Solid iodine sublimes directly into a purple-red gas when heated, without passing through a liquid phase. The purple-red gas will turn back into solid iodine upon cooling.
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?
Solid iodine turns into purple iodine gas when heated.
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.
What is the correct colour for iodine gas?
Iodine gas is a purple or violet color.
What state is iodine at room temperature?
Iodine is a solid at room temperature. It sublimes into a purple gas when heated.
