Why is it necessary to carry out recrystallization near the boiling point of the solvent?
well if you don't re crystilize near the boiling point you will most certainly loose your solute to the glass ware as vapours. if you recrystalize you will remove and separate the components more effectively.
What is the environment of quartzite?
Quartzite is a Metamorphic Rock that undergos extreme heat and pressure forcing pre-existing rocks to recrystalize. It forms through contact metamorphism. It's formed at an igneous intrusion cutting through existing rock in a small area; usually along cooled igneus intrusions.
How do you re-rock?
It depends on whether it was dissolved in water or just crushed up. If it was dissolved in water, it should re-crystalize as the water evaporates. If it was crushed up, aside from dissolving it in water and waiting for it to evaporate off, or melting it in a glass pipe and letting it recrystalize, there's no other way that I can think of to return it to its rock form.
Which types of rocks are not metamorphic rocks?
Sedimentary and Igneous rocks are not metamorphic rocks. Metamorphic rocks however are igneous or sedimentary rocks that have undertaken metamorphism (In extreme heat and/or pressure the minerals are forced to recrystalize) and become metamorphic rocks. If the heat/pressure causes the rock to melt into liquid rock than it is no longer metamorphi, it is igneous. Hope this helps :)
What solution can you use to recrystalize a Mn-salen complex?
You can use a solvent such as a mixture of dichloromethane and methanol to recrystallize a Mn-salen complex. By dissolving the complex in the hot solvent mixture and allowing it to cool slowly, crystals will form, which can then be filtered and washed to obtain the purified product.
Can crack recrystalize in the body and come out through the skin?
No, crack cocaine cannot recrystallize in the body and come out through the skin. Crack cocaine is rapidly metabolized in the body before being eliminated primarily through the kidneys in the form of metabolites. It does not recrystallize and come out through the skin.
How can you make a sugar solution supersaturated?
This kind of technique is used in making fudge, and is very important. You don't want crunchy fudge, do you :) First, you will need sugar (any kind will do), and some hot water or other solvent, but I would use water. So do you know that hot water dissolves more solute than cold water? Well, you then saturate the hot water with the sugar, and SLOWLY (slow is very important) cool down the sugar water mixture. Also, DO NOT AGITATE IT. For example, soda is a super saturated solution, it's super saturated with carbon dioxide. If you shake the soda can (agitating it), the carbon dioxide will separate from the rest of the soda, which causes the (highly entertaining) explosion of soda following. If you agitate it, the sugar will recrystalize and you will have to start over. Now, if it is cooled down fast enough, it will become super saturated, and won't recrystalize. Hope this helped!
How do you re rock meth?
It depends on whether it was dissolved in water or just crushed up. If it was dissolved in water, it should re-crystalize as the water evaporates. If it was crushed up, aside from dissolving it in water and waiting for it to evaporate off, or melting it in a glass pipe and letting it recrystalize, there's no other way that I can think of to return it to its rock form.
How can you make a supersaturated solution with sugar?
To make a supersaturated solution with sugar, heat a pot of water and gradually add sugar, stirring until it dissolves completely. Keep adding sugar until no more will dissolve and you see a layer of undissolved sugar at the bottom. Cool the solution slowly to prevent crystallization, resulting in a supersaturated solution.
What causes looper lines in drawn aluminum?
Looper lines in drawn aluminum are typically caused by inconsistent tension during the drawing process, resulting in uneven stretching and surface markings on the metal. This can be due to equipment issues, improper lubrication, or variations in material properties. Regular maintenance of equipment and adjusting process parameters can help reduce the occurrence of looper lines in drawn aluminum.
How is methamphetamine weighed for sale?
meth is messeasured in grams as with all other drugs. you usually use a digital scale. usually costs around 45-50 dollars a gram. but meth will kill you, trust me ive been around it my entire life. Actually, $45 a gram is cheap. Phoenix Street Prices: 1/4 gram-$20, 1/2 gram-$35, 1 gram-$60. 8-ball-$160 (1/4 oz). There are 3 grades of meth available, so Quality has a bearing on price-these are starting prices. According to Lepidus, Quality has to do with both the ingredients and the process to manufacture the stuff and, of course, the amount of "cut". Since you can add the cut and recrystalize, looking at a shard is not indicative of quality.
Why is benzoic acid is extracted into ether then extracted into an alkali solution prior to being precipitated with strong acid in its preparation with grignard reagent?
Benzoic acid is first extracted into ether to remove impurities or byproducts. It is then extracted into an alkali solution to convert benzoic acid into its water-soluble salt form, making it easier to separate from the non-basic impurities that remain in the ether layer. Finally, the benzoic acid is precipitated with a strong acid to regenerate the pure benzoic acid molecule.
