What products form PbCO3?
Lead carbonate (PbCO3) is formed when lead (II) ions (Pb2+) react with carbonate ions (CO32-) in solution. This compound is sparingly soluble in water and forms a white precipitate when a soluble carbonate salt is added to a lead (II) salt solution.
What type of ions will nonmetals form?
Metals form cations and non-metals form anions.
Which ions are in PB(C2H3O2)2?
The compound PB(C2H3O2)2 is lead(II) acetate, which consists of lead ions (Pb²⁺) and acetate ions (C2H3O2⁻). In this compound, there are one lead ion and two acetate ions, balancing the overall charge of the compound to neutral. Therefore, the ions present are Pb²⁺ and C2H3O2⁻.
What happens when lead 2 nitrate is mixed with H2SO4?
When lead (II) nitrate is mixed with sulfuric acid (H2SO4), a white precipitate of lead sulfate (PbSO4) is formed along with nitric acid as a byproduct. This reaction is a double displacement reaction where the lead ions from the nitrate salt react with sulfate ions from sulfuric acid to form the insoluble lead sulfate.
If the pattern of ions shown here for galena is expanded in every direction how many sulfide ions would sorround each lead ion?
In galena (PbS), the structure consists of lead ions (Pb²⁺) surrounded by sulfide ions (S²⁻). Each lead ion is coordinated by four sulfide ions in a tetrahedral geometry. Therefore, if the pattern is expanded in every direction, each lead ion will still be surrounded by four sulfide ions.
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 ions and chromate ions?
Lead ions = Pb2+Chromate ions = CrO4-2Compound they form is Lead(II) chromate = PbCrO4
Why do you prepare lead iodide from lead nitrate?
Lead iodide is prepared from lead nitrate because lead nitrate contains lead ions and nitrate ions that can react with iodide ions to form lead iodide. This reaction allows for the precipitation of lead iodide, which can then be isolated and collected.
What possible charge can lead acquire as an ion?
Lead can form ions with a charge of +2 or +4.
Does Pb2 plus react with oxygen?
Yes, Pb2+ (lead ions) can react with oxygen to form lead oxide (PbO) or other lead compounds depending on the conditions.
What happens during the electrolysis of molten lead iodide?
During the electrolysis of molten lead iodide, lead ions (Pb2+) are reduced at the cathode to form molten lead metal, while iodide ions (I-) are oxidized at the anode to form iodine gas and release electrons. This process helps separate the elements in the compound by using electrical energy.
Why is lead chromate not soluble in water?
Lead chromate has a low solubility in water due to the strong electrostatic forces between the lead and chromate ions, which hold the compound together in a solid form. These forces prevent the ions from separating and dissolving in water, resulting in poor solubility.
What type of bond does fluorine and lead form?
Fluorine and lead would be likely to form an ionic bond, with fluorine gaining an electron to achieve a stable electron configuration, and lead losing electrons to do the same. This results in the transfer of electrons from lead to fluorine, creating a bond due to the attraction between the positively charged lead ions and the negatively charged fluoride ions.
Why is lead oxide not alkali?
Lead oxide is not considered an alkali because it does not easily form hydroxide ions in water, which is a characteristic of alkalis. Instead, lead oxide reacts with water to form lead hydroxide, which is an amphoteric compound that can act as both an acid and a base.
Aqueous lead chloride reacts with aqueous sodium sulfate to produce a lead sulfate precipitate and aqueous sodium chloride?
The reaction is a double displacement reaction as lead chloride and sodium sulfate exchange ions to form lead sulfate and sodium chloride. The lead sulfate is insoluble in water, forming a precipitate, while the sodium chloride remains in solution as ions. This reaction is used to separate lead ions from a mixture.
What products form PbCO3?
Lead carbonate (PbCO3) is formed when lead (II) ions (Pb2+) react with carbonate ions (CO32-) in solution. This compound is sparingly soluble in water and forms a white precipitate when a soluble carbonate salt is added to a lead (II) salt solution.
How many sulfide ions would surround each lead ion?
