Activated carbon is also known as decolorizing carbon. It is used to remove the colored impurities from the sample. Activated carbon provides a high surface area to absorb colored impurities. http://designer-drugs.com/pte/12.162.180.114/dcd/chemistry/equipment/recrystallization.html

Why use charcoal in recrystallization?
Charcoal is used in recrystallization as an adsorbent to remove impurities from a solution. It effectively adsorbs colored impurities and other organic compounds, helping to clarify the solution and improve the purity of the final crystalline product. By adding charcoal during the heating process, the impurities can be removed before the solution is cooled and crystals are formed. This results in a more refined and higher quality crystal yield.
How would water remove charcoal and sugar in recrystallization?
In recrystallization, water acts as a solvent that selectively dissolves the desired compound while leaving impurities like charcoal and sugar undissolved. Charcoal, being insoluble in water, can be easily filtered out, while sugar, depending on the temperature and concentration of the solution, may dissolve if the conditions are suitable. By cooling the solution slowly, the desired crystals can form, while the impurities remain in the solution or are filtered out. This process helps in obtaining purer crystals of the target compound.
What process could be used to purify potassium chloride?
Crystallization/recrystallization process can be used.
What is the purpose of the sublimation and recrystallization steps?
Recrystallization and Sublimation are two commonly encountered methods of Purification. Several of these are done in the laboratory to obtain a pure sample of a particular organic compound. Recrystallization literally means to crystallize again. Sublimation involves heating the compound at low pressure from one apparatus and and condensing it in another. This is quite the same as distillation but of solid state.
Can charcoal be used as a dehumidifier?
Yes.
What purpose does the addition of finely divided charcoal serve during the recrystallization of impure solids?
The addition of finely divided charcoal during the recrystallization of impure solids serves to adsorb colored impurities and other contaminants present in the solution. This process helps to clarify the solution, resulting in a purer product after crystallization. The charcoal can be removed by filtration before the final crystallization step, ensuring that the resulting crystals are free from discoloration and unwanted substances.

Assuming that charcoal and sugar are the main impurities present in a sample of crude acetanilide explain how recrystallization from water would remove each..?
Recrystallization from water would remove charcoal impurities by dissolving the acetanilide in hot water, as charcoal is insoluble in water. The sugar impurities would also be removed because they are more soluble in hot water than in cold water, so they would remain dissolved during the recrystallization process and be removed in the mother liquor.
Why is sodium chloride not suitable for recrystallization?
The crystallization/recrystallization of sodium chloride from water solutions is frequently used.

What is the purpose of recrystallizing a solid?
Recrystallization is used to purify solids by dissolving them in a solvent and then allowing them to reform into crystals. This process helps remove impurities and improve the overall quality of the solid.
Which charcoal Can charcoal be used as refrigerator deodorizer?
yes
Is Chloroform a good solvent for recrystallization in acetanilide?
Chloroform is not a commonly used solvent for recrystallization of acetanilide. It is more commonly used for dissolving non-polar or slightly polar compounds. In the case of acetanilide, solvents such as ethanol or ethyl acetate are often preferred for recrystallization.
Why charcoal is used in charcoal cavity test?
because it is called a CHARCOAL cavity test.
What is the purpose of putting pieces of charcoal inside the refrigerator?
Charcoal absorbs bad smells. The porous property of charcoal will absorb any odours that are in your fridge.
On a 1999 Bonneville what is the purpose of the charcoal canister filter located under the air filter box?
A charcoal canister is used to trap the fuel vapors from the gas tank. The fuel vapors adhere to the charcoal, until the engine is started, and engine vacuum can be used to draw the vapors into the engine, so that they can be burned along with the fuel/air mixture.
