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

Insoluble particles in a hot solution can be removed by allowing the solution to cool down, causing the particles to settle at the bottom. The clear liquid can then be carefully decanted or filtered to separate it from the insoluble particles. Alternatively, a centrifuge can be used to separate the solid particles from 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?

Filtering a solution while it is hot helps to remove any insoluble impurities or solid particles present in the solution. Hot solutions have higher solubility and are easier to filter, as the particles are more dispersed and can pass through the filter paper more easily. Cooling the solution may cause these impurities to precipitate out, making filtration more difficult.


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

Cocoa powder does not fully dissolve in hot water; it forms a suspension due to its insoluble particles. These particles will eventually settle to the bottom of the container if left undisturbed.


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.
