When lead nitrate is heated which colour fumes are evolved?
When lead nitrate is heated, brown nitrogen dioxide gas is evolved, which gives off a yellowish-brown color.
Are sulfur crystals dangerous to handle or be around?
Yes, sulfur crystals can be dangerous to handle or be around as they can release toxic fumes when heated or exposed to certain chemicals. It is important to take proper precautions when handling sulfur crystals to avoid any potential health risks.
What is an hazardous property of iodine?
Iodine is hazardous because it is toxic if ingested in large amounts, can cause skin and eye irritation on contact, and can release toxic fumes if heated to high temperatures. It should be handled with care and protective equipment should be used when working with it.
What powder reacts with iodine?
Aluminum powder can react with iodine to form aluminum iodide. This reaction is exothermic and can produce purple fumes of iodine vapor.
What is the colour of fumes of nitrogen oxide gas?
Nitrogen is a colorless, odorless, and tasteless nontoxic gas.
What will happen if Iodine Crystals plus Cupric Sulfate plus Calcium Carbonate is heated?
first off DO NOT HEAT IODINE CRYSTALS because they create the same sort of fumes you would fine in a meth lab and it is possible that it can kill you because of its extremely toxic fumes and
When lead nitrate is heated which colour fumes are evolved?
When lead nitrate is heated, brown nitrogen dioxide gas is evolved, which gives off a yellowish-brown color.
What are the effects of iodine fumes?
Inhaling iodine fumes can cause irritation to the respiratory tract and eyes, leading to symptoms such as coughing, throat soreness, and difficulty breathing. Prolonged exposure to high levels of iodine fumes can also cause headache, dizziness, and nausea. It's important to avoid breathing in iodine fumes and ensure proper ventilation when working with iodine.
Are sulfur crystals dangerous to handle or be around?
Yes, sulfur crystals can be dangerous to handle or be around as they can release toxic fumes when heated or exposed to certain chemicals. It is important to take proper precautions when handling sulfur crystals to avoid any potential health risks.

Is chemical change a black solid when heated changes into a purple gas?
Yes, this observation of a black solid turning into a purple gas when heated suggests a chemical change. The change in color and state indicates that new substances are being formed through chemical reactions taking place in the solid material.
What powder reacts with iodine?
Aluminum powder can react with iodine to form aluminum iodide. This reaction is exothermic and can produce purple fumes of iodine vapor.
Does sodium iodide decompose when heated?
Yes, sodium iodide can decompose when heated to high temperatures, releasing toxic fumes of iodine gas. This decomposition reaction is typically seen at temperatures above 600°C. It's important to handle sodium iodide with care and avoid overheating to prevent this decomposition.
Does aluminium give off toxic fumes?
Aluminium itself does not give off toxic fumes at room temperature. However, when heated to high temperatures above 660 degrees Celsius, it can produce fumes that may be harmful to inhale. It is important to take proper precautions when working with heated aluminium to avoid exposure to these fumes.
Does heated aluminum give off toxic fumes?
No, aluminum does not give off any toxic fumes that are harmful in anyway. It does not produce gases nor does it vaporize.
Why should nickel sulphate crystals not be dried in an oven?
Nickel sulphate crystals should not be dried in an oven because they can decompose or melt at high temperatures. This can lead to the formation of toxic gases or fumes, and potentially cause an explosion or fire. It is safer to use a desiccator or drying cabinet at lower temperatures to remove moisture from the crystals.
Can inhaled fumes from heated denatured alcohol cause a false positive on a breathalyzer test?
Yes.
