Sodium bicarbonate

The purpose of this experiment was to prepare azo dyes using the combinatorial approach to show the principles combinatorial chemistry. Using combinatorial synthesis, an array of chemicals can be synthesized by using a parallel synthesis to identify potentially valuable compounds. This electrophilic aromatic substitution reaction involved multiple steps to complete, however, no major techniques were used; only the use of a hot place and an ice bath. The specific azo dyes produced in this experiment

The next test added sodium hydroxide t the unknown solution. This test was used to find out if ammonium (NH4) is present in the solution. The results showed a basic pH from the litmus paper. however, the solution didn’t produce the signature smell of ammonium. This shows that

to the compartment with cathode (the anolyte). DC current is passed and the NaCl is broken into its constituent components with the help of this DC current. The membrane sends Na+ ions to anode compartment which is the catholyte, where it forms sodium hydroxide in solution. Only positive ions are allowed to pass through the membrane in order to prevent mixing of NaOH and HCl. The chloride ions are oxidized to form chlorine in gaseous form and it occurs at anode, which is collected, purified and

To prepare a Ni2+ -NTA-agarose resin column, 5 mL of deionized water and 1.5 mL of Ni2+ -NTA resin slurry (Clontech, His60 Ni Superflow Resin) were added to a glass column. After thorough mixing of the column and resin settling, the water was drained from the column until it reached the top of the resin bed. 10 mL of extraction buffer (50mM NaH2PO4 (pH 7.5), 0.3 NaCl) was added to the column and half of the volume was drained. The column was kept at 4 degrees Celsius until use. Separation of Fumarase

Observing Double Displacement Reactions Purpose: The purpose of the lab is to determine and observe the different double displacement reactions that occur when certain reactants are mixed. Double displacement reactions will be classified with the use of indicators. Introduction: Chemical reactions occur very often in people’s everyday lives. There are six main types of reaction. These include decomposition reactions, synthesis reactions, single-displacement reactions, double displacement reactions

bleach because it is commonly referred to as highly toxic and lethal. We wanted to know more about its chemical makeup to better understand the dangers that come while using Clorox bleach. History: The active ingredient in household bleach is Sodium hypochlorite, and it was discovered by the French chemist Berthollet, in Javel on the outside of Paris, in 1787. He discovered that this chemical had the ability to whiten material quickly and put the product to commercial use in 1914 with great success

Exelon (Rivastigmine Tartrate) is a hydrogen tartrate salt of Rivastigmine that acts as a reversible cholinesterase inhibitor. As a cholinesterase, it is administered in an increasing amount over a set period of time. Through the inactivation of butyrlcholinesterase and acetylcholinesterase, Exelon prevents the breakdown of the chemical acetylcholine which is thought to be important in memory, thinking, and reasoning. Due to these capabilities, it is frequently employed to combat the effects of dementia

pools in either a gaseous or as sodium or calcium hypochlorite. The chlorine is added to water to help prevent people from getting sick from disease-producing microorganisms. The chlorine that is added and reacts with the organic material and metals in the water is the chlorine demand for the water as it will not be available for any disinfection that keeps people from getting sick while in the pool. The residual test is
