How can insoluble particles can be removed from a hot solution?

Boil the solution. it works for salt water. If the particles are insoluble, you don't need to boil anything... just filter the solution using filter paper. (Salt water is soluble -- it is dissolved, but an insoluble particle is a solid in the liquid).


How insoluble impurities removed during recrystallization?

Insoluble impurities are removed during recrystallization by filtration. After dissolving the mixture in a hot solvent and allowing it to cool, the desired compound forms crystals while the insoluble impurities remain suspended in the solution. The crystals are then collected through filtration, separating them from the impurities.


How are soluble impurities removed during a recrystallization?

Soluble impurities are removed during recrystallization by dissolving the impure solid in a hot solvent, then filtering the hot solution to remove insoluble impurities. The solution is then cooled slowly, allowing the pure compound to crystallize out while the impurities remain in solution. The pure crystals can be separated from the solution by filtration.


Why is it necessary to filter the solution while its hot?

If you have a solution, you have a solute (usually a solid) dissolved in a solvent. When you cool the solution, you increase the odds of the solute reassociating, thus forming solid crystals that you can then filter out to recover the product.


Does real cocoa powder fully dissolve in hot water or is it just a suspension?

It dissolves for the most part. Add enough, and it soon becomes more of a mixture than a solution.


How does the recrystallization produce remove solvent soluble impurities?

Soluble impurities are removed by a process of vacuum filtration


Which Metallic Chloride is Insoluble in Cold and hot water?

Silver chloride (AgCl) is insoluble in both cold and hot water.


Why hot tea is a solution?

Yes, It is a mixture of water, and tealeaves. A chemical reaction does not occur.


Is hot chocolate a suspension a solution or a colloid?

Hot chocolate is a colloid. It is a mixture where small particles of chocolate or cocoa are dispersed throughout a liquid (milk or water) to form a stable mixture.


When a hot saturated solution is cooled?

When a hot saturated solution is cooled, the solubility of the solute decreases, causing excess solute particles to form a precipitate. This is known as recrystallization, where the solute molecules come together and solidify to form crystals in the solution.


Why is it necessary to filter the benzoic acid solution while hot?

Filtering the benzoic acid solution while hot helps to keep the compound in solution as it cools, preventing it from crystallizing and clogging the filter paper. This ensures that all impurities are removed from the solution before it solidifies.


Why did the penny turn silver after a few minutes in the hot solution?

The hot solution likely removed the copper oxide layer on the penny, revealing the silver-colored zinc underneath. Heating caused a chemical reaction that removed the tarnished layer on the penny, giving it a shiny appearance.
