clinical applications of crystallization and decolorization?

well this is related to pharmacy.it is widely used in medicine preparations.crystallization is a unit process employed for purity of the drug n for easy consumption by various routes.decolorisation is done by using charcoal powder coz usually drugs might b incorporated with various coloring agents which will act as impurity to drug n might reduce its viability.hence it is decolourized.both r basically some important unit processes employed for the purity of drug or medicament

You can evaporate, or distill off the water.  Then you'll get the CuSO4, along with any non-volatile impurities that may be present.  Or you can do a recrystalization.  You boil the solution until the CuSO4 just starts to crystalize out.  Then you let the solution cool.  As it cools, the solubility of the salt decreases, and more & more of it crystalizes.  When cooling, you may end up with a super-saturated solution, instead of crystals being formed.  In that case, scratching the inside of the beaker with a glass rod will initiate the crystalization process.  With recrystalization, the product is also purified.

The biuret test, use an equal volume of potassium or sodium hydroxide as volume of protein, followed by 2 drops of copper sulfate solution and mix. A positive result will produce a purple coloration...

You could dissolve the crystal compound in water and measure the temperature change and specify whether there is an endothermic or exothermic change.  \n\nYou will need a thermometer.  Be careful as some crystal compounds are violently exothermic when dissolved in water.\n\nAndy

I don't think there is any. Check out this link:\nhttp://en.wikipedia.org/wiki/Vitiligo#Treatment

disintegration, dispersion, interruption\n\nAny of these will work....

Compound W.\nThere is also a new product on the market where you can freeze them off.  Uses similar treatment that doctors use.\n\nI've also heard that the duct tape thing works well.

Hmmm, what exactly do you mean by INSTRUMENTAL techniques? As the guy before me said, you could titrate it against a strong coloured oxidising agent such as acidifies potassium permanganate. But you can't really get the concentration from a spectrophotometer, for example, since peroxide (H2O2) doesn't absorb light.\nI guess you could thry using a NMR spectrometer for the job, or some kind of chromatography, but titration is by far the safest and easyest.

Hello\n\nI hope you are feeling better soon.\n\nIt does not seem to be a major concern.  Just something to note if you are having urine tests while taking.\n\n- (cited below) While crystalluria has been observed in some intravenous rat studies, urinary crystals are not formed in the bladder, being present only after micturition and are not associated with nephrotoxicity. \n\n- (cited below) It is tempting to associate crystals with a risk of urolithiasis, but the majority of patients with a crystalluria do not have and will not develop kidney stones.\n \nGet better soon :-)

Depends on the ingredient.  Usual procedure is to chop the plant in a blender and extract the active principle with a suitable solvent, and then refine the extract with fractional crystallization, distillation, or other such means.

First off... dihydrogen monoxide is ....WATER!!!!!!!!!\n\nThe smaller the salt crystals you are trying to dissolve, the more rapidly they will dissolve... due to increased surface area.

yes its safe to use the salicylic acid breaks down the bonds between the dead surface cells and the micro crystals help to remove the dead skin cells from the surface\njust be careful not to rub too much or use more often than it recommends\none word of warning try not to get any in your eyes

What do you want to treat it for? Do you wnat to soften it? Remove salt? Sterilise it? Remove pesticides? Remove colloids?\n\nNothing short of an activated charcoal filter or distillation will do al those things
