Sulfanilamide Introduction The purpose of this experiment is to prepare sulfanilamide from p-Acetamidobenzenesulfonyl chloride. This will be done using reflux‚ vacuum filtration‚ and melting point determination. Experiment Scheme6 Figure 1. Reaction equation.6 A hot water bath was prepared in a fume hood using a 250-mL beaker. 2.5 g of p-acetamidobenzenesulfonyl chloride was placed into a 50 mL Erlenmeyer flask and 11 mL of dilute ammonium hydroxide solution was added to it.

and our reactions to it. Since sodium-chloride is nontoxic our response to the dosage was measured by taste. This same method can be seen in medical studies for new drugs. Instead of students the doctors use mice and they test for the mice’s reaction to the medicine. Instead of testing the mice’s taste‚ they look for negative/positive side effects the mice might have Intro Different salts can elicit all five basic tastes‚ e.g.‚ salty (sodium chloride)‚ sweet (lead diacetate‚ which will cause

balance of electrolytes will eventually affect the amount of water in your body‚ blood acidity‚ muscle action‚ and other important processes. Electrolytes regulate the body’s fluid intake. There are three types of electrolytes; sodium‚ potassium‚ and chloride. Electrolytes are present in the human body‚ and the balance of the electrolytes in our bodies is essential for normal function of

As long as you are alive‚ your body will constantly metabolize organic molecules and produce waste products. If you can not get rid of these metabolic waste products‚ they will accumulate to toxic levels and poison your body. The urinary system is very important because it perform the essential function of getting rid of these metabolic wastes. Main Structures of the Urinary System The main structures that make up the urinary system are two kidneys (contains nephrons)‚ two ureters‚ one bladder‚ one

Precipitation Titration Mohr Method Experimental The chloride ion (Cl-) is an important anion found in solids and solutions. In this experiment‚ the amount of chloride ion in an unknown sample J (NaCl + KCl mixture) of water using the Mohr method is determined‚ which relies on the solubility differences of two anions and the titration endpoint of a precipitate. The net ionic reaction during the titration is as follows: Ag+ + Cl- → AgCl(s) The Ksp for AgCl is 1.8 x 10-10 and

fillings‚ and sodium chloride. To remove the iron fillings from the mixture I used a magnet and scanned it across the entire mixture and the magnet forced picked up all the iron pieces. Then to separate the sand from the rest of the mixture I heated the mixture with water in a beaker and when I poured the heated liquid into a cup the sand remained in the bottom of the beaker. Lastly to separate the benzoic acid and sodium chloride I used a filtration system and the sodium chloride and water drained

Inorganic chloride liberated by Pleurotus sajor caju was 230.9% and chemical oxygen demand (COD) was reduced by 61.3% on 10 day treatment. In pilot scale treatment maximum decolourization was obtained by Pleurotus sajor caju 60.1% on 6 day of incubation. Inorganic chloride was increased by 524.0 mg/l and the COD was reduced by 1442.0mg/l (57.2%) by Pleurotus sajor caju on day 7 of incubation
