One method to separate lead(II) ions and copper(II) ions from an aqueous solution is through precipitation. By adding a solution containing a precipitating agent specific for lead(II) ions, such as potassium chromate, lead chromate will precipitate out of solution while copper remains in solution. The two components can then be physically separated by filtration.
What else can I help you with?
What is the behavior of copper ions in aqueous solution?
Copper ions in aqueous solution tend to form complexes with water molecules, resulting in a blue color. They can also react with other ions in the solution, such as chloride or sulfate, to form insoluble precipitates. Additionally, copper ions can undergo redox reactions, where they can be reduced or oxidized depending on the conditions of the solution.
What are the spectator ions when copperII chloride reacts with aqueous ammonium phosphate?
The spectator ions in the reaction between copper (II) chloride (CuCl2) and aqueous ammonium phosphate ((NH4)3PO4) are Cl- and NH4+. These ions do not participate in the chemical reaction and remain unchanged in the solution.
What is the color of light absorbed by an aqueous solution of copper sulphate?
An aqueous solution of copper sulfate absorbs light in the blue-green region of the spectrum. This is because copper ions in the solution absorb light of longer wavelength, leaving behind the blue-green color.
Why does the precipitation of copper ion dissolve in excess aqueous ammonia?
Excess aqueous ammonia forms a complex with copper ions called tetraamminecopper(II) complex, [Cu(NH3)4]2+, which is soluble in water. This complex formation reduces the concentration of free copper ions in solution, causing the precipitation of copper ions to dissolve.
Is copper II Hydroxide a base?
Yes, copper II hydroxide is a base. It is an insoluble base that forms when copper ions react with hydroxide ions in an aqueous solution, leading to the precipitation of the copper II hydroxide compound.

Why aqueous copper sulphate solution conduct electricity but solid copper sulphate does not?
Aqueous copper sulfate solution contains free ions (Cu2+ and SO4 2-) that can carry electrical charge and allow the solution to conduct electricity. In contrast, solid copper sulfate does not contain free ions and is unable to conduct electricity because the ions are locked in a fixed position within the solid lattice.
What is the formula for ammonium dihydrogenphosphate?
NH4H2PO4. Note that these are two separate ions in an aqueous solution.

What ions do all acids produce in aqueous solution?
All acids produce hydrogen ions (H+) in aqueous solution.
Can copper chloride solution conduct electricity?
Yes, copper chloride solution can conduct electricity because it contains mobile ions that are capable of carrying electric charge. When an electric field is applied, the copper ions and chloride ions in the solution can move towards the oppositely charged electrodes, allowing the flow of electric current.
How do you use steel wool to remove the cu 2 plus ions from an aqueous solution of copper ll sulfate?
Oh, dude, it's like this - you take the steel wool and just plop it into the copper sulfate solution. The steel wool reacts with the copper ions, forming a solid copper metal on the wool and leaving the solution without the Cu2+ ions. It's like magic, but with science!
Is salt plus vinegar is an example of aqueous solution?
Yes, in this case you would have an aqueous solution of sodium chloride and acetic acid.
