A Chemical change is any form of chemical reaction changing the state of the matter involved. When you fry an egg, you are making a reaction between the heat and the chemicals that make up the egg. Therefore once you have fried that egg, you have completed a chemical reaction. This is why it's a chemical change when you fry an egg.
Answer: Scientists make designs based on engineering knowledge and
then make it available for public use.
Charcoal (aka. Norit, activated carbon) is added during recrystallization to secure high molecular weight, colored impurites. Charcoal is added once you have a hot saturated explanation of the desired product, and, once added, needs to be released (along with the adsorbed colored impurities) by hot gravity filtration.
<h3>What is the purpose of counting activated carbon to the cordial solution during a recrystallization?</h3>
Added during a recrystallization to bind high molecular weight, colored impurites.
<h3>What is the purpose of charcoal in purification of chemicals?</h3>
The huge surface area of activated charcoal gives it countless connecting sites. When certain chemicals pass next to the carbon surface, they stick to the surface and are entangled.
Activated charcoal is good at trapping other carbon-based pollutants ("organic" chemicals), as well as things like chlorine.
