How do you separate a mixture of sodium chloride and copper 2 chloride and how do you prove that you've separated it?
To separate a mixture of sodium chloride and copper (II) chloride, you can use a process called precipitation. By adding a solution of sodium hydroxide, the copper (II) ions will react to form a blue precipitate of copper (II) hydroxide, leaving sodium chloride in solution. To prove that you have separated the two compounds, you can filter the mixture to separate the solid copper (II) hydroxide from the liquid sodium chloride solution. You can then confirm the presence of copper (II) ions in the precipitate using chemical tests such as flame tests or by dissolving the precipitate and performing further confirmatory tests.
Did the evidence obtained in the silver nitrate tests of the 3 solutions prove conclusively that the residue actually was potassium chloride?
The evidence obtained from the silver nitrate tests strongly suggests that the residue is likely potassium chloride. The formation of a white precipitate in the silver nitrate tests is characteristic of chloride ions reacting with silver ions. However, further confirmatory tests may be needed to conclusively prove the identity of the residue as potassium chloride.
When methanol is burned and leaves a residue a physical or chemical change?
When methanol burns and leaves a residue, it undergoes a chemical change. The burning of methanol involves a combustion reaction, where the methanol is reacting with oxygen to form new substances, such as carbon dioxide and water. The residue left behind is a result of this chemical reaction.
What is the definition of residue in science?
In science, residue refers to the portion of a substance that remains after a process has been completed. It can be in the form of solids, liquids, or gases that are left behind as a result of a chemical reaction, filtration, or separation process. Residues are often analyzed to understand the composition of the original substance or to determine the effectiveness of a process.
Did the evidence in the silver nitrate tests of the three solutions prove conclusively that he residue actually was potassium chloride?
Yes, the silver nitrate test is a confirmatory test for chloride ions, which react with silver ions to form a white precipitate of silver chloride. Therefore, if the silver nitrate test produced a white precipitate in all three solutions, it provides strong evidence that the residue was indeed potassium chloride.
What is caustic salt?
Sometimes the mixture of sodium chloride and sodium hydroxide is called caustic salt; it is a residue of the electrolysis.
What residue is left after sodium chloride is heated?
After 1 413 0C pure sodium chloride is vaporized without any residue.
What evidence led you to formulate the composition of the solid residue after heating the marble chip?
The evidence is by chemical analysis.
What is the composition of the residue from the production of super glue?
It's cyanoacrylate residue.
What is the chemical residue left in the charring test?
the charring test would result a Gay person, or also known as Homosexual, the chemical residue that the "charring" test proves to be very effective in metamorphing a male human, into a gay or homosexual person.
What is the residue when sodium chloride water solution was heated to dryness?
When a mixture of sodium chloride and water is heated to dryness, the residue is sodium chloride, because the boiling point of sodium chloride is much higher than the boiling point of water.
How do you separate a mixture of sodium chloride and copper 2 chloride and how do you prove that you've separated it?

Is salt dissolving in water and leaving a white residue a physical or chemical change?
Salt dissolving in water is a chemical change, the white residue is left when the water gets saturated by the salt and the salt starts to come out of solution to gain equilibrium. The residue can also be left behind when boiling off the water.
How will you separated the following mixture and water ammonium chloride sodium chloride?
1. Evaporate the solution, water being removed. 2. Sodium chloride and ammonium chloride remain as a solid residue. 3. Heat this residue. 4. After 340 0C ammonium chloride is decomposed and gases released. 5. Sodium chloride remain single.
What liquid leaves a residue of sodium chloride when evaporated?
Saltwater, which is a mix of water and dissolved sodium chloride, will leave a residue of sodium chloride when it evaporates. The water evaporates, leaving behind the salt as a white or clear crystal residue.
What can happen if you individual sodium and chloride ions when the water in a saltwater solution evaporates?
Sodium chloride remain as a crystalline residue.
What is the residue in a separation of sodium chloride and sulfur?
Putting this mixture in water sodium chloride is dissolved; sulfur is not soluble in water.
