    Essay On Stoichiometry

    • 799 Words
    • 4 Pages

    Background : Stoichiometry is the relationship between the relative quantities of substances taking part in a reaction or forming a compound, typically a ratio of whole integers. In the lab that I did with my group we used stoichiometry to find out the decomposition of sodium biocarbonate. Sodium carbonate is just another name for baking soda, and that is what we used on our lab. Baking soda is also used in some food items, such as pancakes, waffles etc… When the baking soda is being heated…

    a reference standard correspondingly. Compatibility studies The compatibility of drug and polymers under experimental condition is significant precondition before formulation. Incompatibility between drugs and excipients can modify stability and bioavailability of drugs, thereby, moving its safety and efficacy. Study of drug–excipients compatibility is a vital process in the growth of a stable dosage form. Drug–excipients compatibility testing at an early stage helps in the assortment of…

    Diels-Alder Reaction Objective: The objective of this lab was to do a diels-alder reaction using anthracene, maleic anhydride, and xylene to create 9,10-dihydroanthracene, 10-, -succinic acid anhydride. Experimental: Anthracene (1.00g, 5.61x 10-3 mol), maleic anhydride (0.75g, 7.61x 10-3 mol), xylene (5mL, 4.71x 10-2 mol), and a stir rod were added into a round-bottomed flask. The round-bottom flask was then moved to the hood where the it was attached to a distillation column, placed on…

    activity of 1 in copper and phosphine free Sonogashira coupling reaction in water, we optimised the conditions for the reaction between p-Iodonitrobenzene and phenyl acetylene in absence of copper(I) salt. It was observed that at a temperature of 50°C (among 25°C, 50°C and 80°C) the bases used, piperidine and Et3N (among NaHCO3, Na2CO3, K2CO3, KOH, Et3N and piperidine) give high yield under aerobic conditions (Table 1). Secondly, parallel reaction between phenyl acetylene and p-Iodonitrobenzene…

    of equivalents of glycidol reacted with carbazole. Carbazole reacts with glycidol without catalyst. The process is exothermic and thus needs control of temperature. Reaction of carbazole with glycidol requires excess of glycidol, the best molar ratio is 1:7. When lower excess of glycidol is used, the carbazole precipitates from reaction mixture. This semiproduct obtained from carbazole and…

    • 4 Pages

    Iodoform, CHI3 is formed in methyl ketone, which gives yellow precipitate when there is a positive reaction. Iodoform test is performed in basic condition as the alpha proton is eliminated in basic condition. The elimination of the alpha proton causes the alpha carbon to be nucleophilic and allows it to attack iodine molecule. The presence of the iodine…

    water soluble complex. A slope value of less than one indicated that an inclusion complex in a molar stoichiometric ratio of 1:1 was formed between the drug and β-CD in solution. The stability constant (718.58 M–1), computed from the slope and intercept of the phase solubility diagram, indicated considerable interaction between the hydrophobic drug and the hydrophobic cavity of β-CD. The values of stability constants described in the literature ranged from 100 to 20,000 M–1 for…

    Most corrosion is an electrochemical reaction. Anything that affects the speed of the chemical reaction will in turn affect the amount of current flow, which will affect the rate of corrosion. The rate of corrosion is directly proportional to the amount of current in the electrochemical corrosion cell. If the current can be measured accurately, then an exact calculation of the metal loss can be made. 2.2.1 ELECTRICAL EFFECTS ON THE RATE OF CORROSION Any issue that have an effect on the…

    reconstruction. Hence, understanding the mechanism of exchange and determination of rate of mineral-fluid exchange in foraminiferal calcite are critical for accurate estimation of the extent of post-formational alterations on carbonate-based proxies. The reaction rates estimated in most of the atom exchange experiments are under the basic assumption of homogeneous exchange at equilibrium (illustrated in the Appendix C, section C1) (e.g., Moller and…
