Why isn't it good to use a large quantity of activated charcoal in recrystallization to remove impurities?

It is not good because it binds to the compound, and it will cause sample loss.

∙ 9y agoMore is not better because the excess charcoal may bind to the substance you are trying to purify by forming LDF bonds when a H is lost from either charcoal or substance to purify.

∙ 13y agoThe charcoal will stick to trace impurities in your mixture so when a gravity filtration is done, the charcoal and trace impurities will be removed resulting in pure product.

How do you make coconut shell charcoal in huge quantity?
Burn lots of coconuts.
Are silver fillings valuable?
That depends entirely on the quantity, as with anything. Silver is currently worth around £23.67 per troy ounce ($38.50) Which is particularly high. However a collection of silver fillings are likely to be somewhat lighter and containing impurities, therefore rendering them as not particularly valuable.

What is extrinsic conductor?
Impure semi conductor material are called extrinsic semi conductor as there a small quantity of foreign particle is present. Two types of impurities are added to an extrinsic semi conductor. When impurities belonging to third group are called as trivalent or acceptor impurities such as boron, aluminum, indium or gallium when these impurities are added in pure semi conductors they form p-type semi conductor. And similarly when impurities belonging to group fifth called as penta valent or donor impurities such as arsenic, antimony, bismuth or phosphorus are added to a semi conductor they form N-type semi conductor .

Process of making charcoal made in waterlily?
Most anything containing a decent amount of carbon can be turned into charcoal. the basic principle is to bake off the impurities (undesired material) and to leave the carbon behind. This can be achieved a couple of ways. By igniting the material and the quenching it once the impurities are burned off but before the carbon burns off. This method is the most basic, however it doesn't always yield the best results as you loose some of the carbon to burning or not all of the impurities will burn off. Or you can bake your desired material. This provides the best end product as none of the desired material is lost to burning and all the impurities are burned off. It does require extra fuel to bake with though and so it can be inefficient. you can supplement the fuel being burned with the gasses that are produced by baking to make the process more efficient. The last method is the Light and burry method. This is a mix of both previous methods. You light your fuel on fire, and once it has produced sufficient heat you deprive the material of oxygen (burying is one of the most common) this will use the heat from the fire to bake it's self. This process can take a very long time depending on the size of the material and the quantity.
What is the effect of impurities on the melting point of ice and the boiling point of water?
The freezing point of water decreases when the number of dissolved molecules (or better particles) in the solvent increases. This is called freezing point depression and you can easily find the relation between the quantity of particles dissolved and the freezing point on Wikipedia.
