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 else can I help you with?
The element which gives you violet vapour on heating it?
Iodine is the element that gives off violet vapor when heated.
Which element gives off a violet vapor when heated?
Potassium (also named Kalium), symbol K.
What is released as vapor when hydrates are heated?
When any liquid is heated and a vapour is given off, it is usually a gaseous form of that liquid. Although it can usually result in water being given off if a hydroxide and another diatomic molecule is heated eg. OH and CO3 (these are only the diatomic molecules) into H20 and CO2.Hydrate is a term used in inorganic chemistry and organic chemistry to indicate that a substance contains water. hence water is the vapour that is given off
What substance is given off when the salt solution is heated gently?
Water vapor is given off when a salt solution is heated gently. As the solution heats up, the water molecules begin to evaporate, leaving behind the salt particles.
What happens when petrol is heated?
It becomes less viscous, and gives off more vapors(evaporation).
What is a solid nonmetal that gives purple vapor on heating?
Iodine is a solid nonmetal that gives off purple vapor when heated.
What element is is shiny black solid but gives off a purple vapor when heated?
Iodine on heating gives off dense purple vapor.
This shiny nonmetal gives off purple vapors?
The shiny nonmetal that gives off purple vapors is iodine. When heated, solid iodine sublimes directly into a purple vapor without first turning into a liquid.
What gas is given off when Potassium Hydroxide and Sodium Hydroxide heated?
When Potassium Hydroxide is heated, it gives off water vapor (H2O). When Sodium Hydroxide is heated, it also gives off water vapor (H2O).
The element which gives you violet vapour on heating it?
Iodine is the element that gives off violet vapor when heated.
What is shiny black solid but gives off a purple vapor when heated.?
You think to iodine.
What is an element that is a shiny black solid and gives off a purple vapor when heated?
Iodine ------------------------------------------- The element you describe sounds like iodine, a good test to make sure that it is iodine is to see if the substance sublimes. This means a solid sample of iodine will turn straight from a solid into a gas with no liquid stage.
Which element gives off a violet vapor when heated?
Potassium (also named Kalium), symbol K.
What element is shiny nonmetal and gives off purple vapors?
The element described is likely iodine. Iodine is a shiny nonmetal that sublimes into purple vapors when heated.
What is the colour of the fumes given off when crystals of iodine are heated?
The fumes given off when crystals of iodine are heated are purple in color.
What does it mean when a crystal when heated gives off water vapor and becomes a powder?
When a crystal gives off water vapor and turns into a powder upon heating, it typically indicates that the crystal is a hydrated salt (contains water molecules within its structure). The heating drives off the water molecules, leading to the breakdown of the crystal structure and formation of a powder.
Can you change baking soda into washing soda?
Yes you can. If baking soda is heated to high temperatures (300-400 F) it turns into washing soda. It gives off carbon dioxide and water vapor.
