EARN MONEY WITH MAKING PRUSSIAN BLUE

      
Prussian blue used industries :
                                             pharmaceutical industries 
                                            dye chemical industries                                                                                                    ink industries  
            annually 12,000 tonnes is required only for ink industry 
uses of Prussian blue:
  1. the Prussian blue is widely used in oil,water color and dyeing industries 
  2. it is used for production of black and bluish inks
  3. Prussian blue ability to absorb the monovalent metallic cations ,which type of cation is toxic to our body.
  4. it is used for chelating agents for certain toxic heavy metals like thallium or radioactive caesiuim 
  5. it is used for finds the iron sample in the bio specimens.
  synthesis of Prussian blue :

chemicals required :

  1. distilled water 
  2. ferric chloride(FeCl3)-4 grams
  3. potassium ferrocyanide-1.5 grams
  4. filter paper -1
  5. 100ml measuring jar   
safety notes :

ferric chloride is an irritant and is hygroscopic, please keep the bottle tightly capped.

procedure:

  1. prepare a saturated solution of ferric chloride by placing 3.7g of ferric chloride in a small beaker with 5ml distilled water .
  2. separately prepare a saturated solution of potassium ferrocyanide  by placing 1.39g in another beaker with 5ml distilled water.
  3. make a Prussian blue by pouring the potassium ferrocyanide solution into the beaker with the ferric chloride solution .stir with a glass rod , filter the mixer and then dry it in air and stored for packing.

METHYL ISOCYANATE (BHOPAL DISASTER CHEMICAL EQUATION )

Bhopal disaster was occurred by one simple chemical reaction in methyl isocyanate storage tank . (note-MIC-METHYL ISOCYANATE)  MIC is used for the production of carbamate pesticides and also rubber and adhesives. MIC is a colorless liquid and pungent order .    it's boiling point is 38.3 degree Celsius (100.9 F) approximately our body higher temperature .  MIC is reacted with water ,this leads to formation of 1,3 dimethyl urea and carbon dioxide with evolution of heat .  this reaction is continued, this leads to increases the temperature of MIC stored tank . at that temperature all MIC was transforming  liquid to gas form . slowly MIC gas was evolved out through the smoke Aerial tower . because of high molecular weight of the MIC and high denser than the air ,it starts spread lower feet to ground . this two things only kills the lacks of people .1) is reaction with water 2.) is high molecular weight of gas.

REASON FOR ADDING GYPSUM IN CEMENT

upon mixing cement powder with water ,part of  the tricalcium aluminate and gypsum dissolved and react together forming ettringite . the ettringite crystal on the surface of the cement particals are so fine that they cannot bridge the gap between structure .this is the basis of the delay in solidification upon adding gypsum to cement . if we mix cement with water without adding gypsum the tricalcium aluminate immediately reacts with water to form calcium aluminate hydrate . which fills the gap between the cement particals with large crystals and leads to very rapid solidification of the cement slurry

CHEMISTRY OF BASIL AND IT'S MEDICINAL USES

  Scientific name:- Ocimum basilicum L Family:- lamiaceae The major organic chemical compound present in the basil is estragole.          estragole  Medicinal properties:- Antimicrobial Antispasmodic Medicinal uses:- Because of antibacterial properties of basil, it has been used as a antibacterial agent to kill the bacteria like E.coli bacteria and many other bacterias. It is Used as a antifungal agent against aspargillus and rhizocaticol It has been used in the treatment of gonorrhea, dysentery, chronic diarrhea, wound healing, pimples, skin infections and against different varieties of bacterial diseases. It is a very good source of beta carotene. Normally beta carotene help to prevent damage to the cells by free radicals. Magnesium is essential mineral present in basil which helps the heart and  blood vessels to relax, improving blood flow. Other nutrients and also found in basil include iron calcium potassium and vitamin c. Other applications:...
