What colour Residue will be formed when Magnesium burns in oxygen?
Blue
What are the forms of lead residue?
Lead residue can exist in various forms, including dust, particulate matter, fumes, and deposits. These residues can be left behind from processes such as lead-based paint removal, soldering, or firing ranges. Lead residue poses health risks if inhaled, ingested, or absorbed through the skin.
What color is lead iodide?
Lead(II) iodide is yellow in colour
What element in organic compound causes the formation of black residue?
Incomplete combustion of carbon-containing compounds, such as hydrocarbons, can lead to the formation of black residue due to the production of elemental carbon (soot). This soot is responsible for the black color seen in the residue.
Which gun shot residue metal will be detected by atomic absorption but not neutron activation?
Lead is a metal in gunshot residue that can be detected by atomic absorption but not neutron activation. This is because atomic absorption spectroscopy relies on the absorption of light by ground-state atoms, which lead exhibits. Neutron activation analysis, on the other hand, requires the irradiation of samples with neutrons to induce radioactivity, which is not applicable to lead.

Which nitrates on thermal decomposition gives black residue?
Lead nitrate on thermal decomposition gives a black residue because it forms lead oxide.
Is acidic cleaner or alkaline cleaner better for cleaning lead residue?
Alkaline cleaners are more effective at removing lead residue compared to acidic cleaners. Alkaline solutions can help solubilize lead compounds for easier removal, while acidic cleaners may react with the lead residue to form insoluble salts that are harder to remove.
When crystals of ferrous sulphate are strongly heated residue obtained is in which colour we get?
The residue obtained when crystals of ferrous sulphate are strongly heated is reddish-brown in color. This residue is a compound called ferric oxide or iron(III) oxide.
What colour after lead nitrate heated?
lead oxide
What colour is the positive lead?
On what?
What is Lead iodide?
Lead(II) iodide is yellow in colour
When potassium iodine is placed in lead nitrate what is the color of the residue?
Yellow; the insoluble precipitate Lead(II) iodide is created
What color is lead iodide?
Lead(II) iodide is yellow in colour
What term is used to describe the unreacted lead oxide?
The unreacted lead oxide is typically referred to as "residual lead oxide."
What flame colour do get when you burn lead?
blue
