Is cromate soluble?
Chromate salts are typically soluble in water, except for certain heavy metal chromates like lead chromate and silver chromate, which are insoluble.
Why cannot agitate when Recrystallization?
Agitation during recrystallization can introduce impurities by causing crystals to form too quickly, trapping impurities within the crystal lattice. It can also lead to mechanical losses due to crystal breakage. Overall, agitation disrupts the controlled crystallization process, resulting in lower purity of the final product.
How do you purify lead?
Lead can be purified by either electrolysis or chemical refining. In electrolysis, lead is placed as an anode in an electrolyte solution and a direct electric current is passed through. This process removes impurities that are deposited at the bottom. Chemical refining involves reacting impure lead with chemicals to form lead compounds, which are then removed.
Two colorless solutions were mixed. a yellow precipitate was formed.what possible reactants were mixed and what was the yellow coloured precipitate formed due to?
The possible reactants could be sodium thiosulfate and silver nitrate, forming a yellow precipitate of silver sulfide. Another possibility is mixing potassium chromate and lead(II) nitrate, forming a yellow precipitate of lead chromate.
Can lead be returned to uranium?
No, lead cannot be converted back into uranium. Once uranium has decayed into lead, it cannot be reversed.
What is the color of lead chromate?
Lead chromate is typically yellow in color.
What are the elements in lead chromate?
The elements in lead chromate are lead (Pb), chromium (Cr), and oxygen (O). Lead chromate has the chemical formula PbCrO4.
What is the formula for leadII chromate?
Lead(II) Chromate = PbCrO4
What is the formula for the compound formed by lead(ii) ions and chromate ions?
Lead ions = Pb2+Chromate ions = CrO4-2Compound they form is Lead(II) chromate = PbCrO4
What is the formula for the compound formed by lead II and chromate ions?
The compound formed by lead (II) and chromate ions is lead(II) chromate, with the chemical formula PbCrO4.
What is the formula for the compound formed by lead ions and chromate ions?
The formula for the compound formed by lead ions (Pb^2+) and chromate ions (CrO4^2-) is PbCrO4, which is lead(II) chromate. This compound is a yellow solid that is sparingly soluble in water.
Is there any way to make lead chromate?
by the reaction of lead nitrate with potassium chromate or potassium dichromate
What is the chemical formula of lead II chromate?
The chemical formula of lead II chromate is PbCrO4.
What is the name for PbCr2O7?
Lead (II) Dichromate
Is lead chromate an ionic or covalent compound?
Lead chromate is an ionic compound. Lead (Pb) is a metal and chromate (CrO4) is a polyatomic ion, so they form an ionic bond by transferring electrons.
Is lead chromate soluble?
Lead chromate is sparingly soluble in water; it is slightly soluble in acids and more soluble in alkalis. However, lead chromate is considered highly toxic and should be handled with care due to its potential environmental and health risks.
What is pbcr04?
Lead Chromate
