Identification and Synthesis of an Unknown Ionic Compound
28th October 2015
The chief objective of this experiment was to identify the unknown compound. The following tests were conducted to eventually establish the identity of the compounded: qualitative solubility tests, anion and cation tests, flame test, and the formation of a precipitate. The physical properties of the unknown ionic compound found that it has no smell and was…
This experiment was divided into two parts: one part was to observe the properties of a single Alka Seltzer tablet and the second part was to find the percentage of CO2.
In the first part of the experiment, the visible properties of Alka Seltzer were observed and recorded. Each Alka Seltzer contains the same three ingredients: 325 mg of Aspirin, 1000 mg of Citric Acid, and 1916 mg of Sodium Bicarbonate.
Two of Alka Seltzer’s ingredients, Citric Acid and Sodium Bicarbonate (Baking…
Bast was immersed in 0.85% solution of Triton X-100 at 40 ⁰C for 10 min, followed by soaking in sodium hydroxide (NaOH) solution at varies concentrations (1, 2 4, 6 and 8%) at 100 ⁰C for 60 min. For enzymatic retting, the fiber was treated with chelating agent, enthylenediamine-tetraacetic acid, then immersed in 0.85% solution of Triton X-100 at 40 ⁰C for…
Nimodipine 0.02% solution contains the following excipients:
Ethanol 96%, Macrogol 400, sodium citrate, citric acid, Water for Injections Ph. Eur.
These excipients consist of properties that aim towards the proper functionality of Nimotop. They consist of inherent stabilities that cause little or no effect in the stability of the drug and they do not have any acute or chronic toxicity. The excipients are also added into the Nimodipine 0.02% solution to enhance the biological…
relationship and Empirical formula of a Hydrate
The purpose of this lab experiment is to determine the molar ratio between substances, and to write chemical equations. The second experiment is to determine the ratio of water in copper, and magnesium, which is obtained through burning the vapor using the Bunsen burner.
Because the experiments were conducted online there wasn’t any use of materials, only digital ones, for these labs to be performed. Only the registration…

Exp 12: Thermodynamic Analysis of Chemical Equilibria
The reaction being done with borax and HCl is an acid base reaction. The K constant expression of the reaction is Kc = [Na^+][B4O7^-2]. A titration is needed for this experiment because when a strong acid with a known concentration is added to a weak base, the unknown concentration of the weak base can be found, which can then find the moles of the weak base, which can then find the Kc. The first law of…
The theoretical treatment of the equilibrium structure of the derivatives was based on the DFT method using the functional B3LYP with the base 6-311 ++ G (d, p). To distinguish the molecular electrostatic potential surface (MESP), we used the principle of HSAB (Hard Soft Acid and Base), in order to have the centers of activity of a molecule and the effects of substitution on the systems of pyrazolooxazine. These have anti-inflammatory activities. In our work, we have applied methods of…
220.127.116.11. Hydrogen sulphid test (MacFaddine, 1980):
Tubes of triple sugar iron agar media were inoculated by suspected culture through stabbing into the butt and the slant then covered with sterile melted paraffin wax and incubated anaerobically for 48 h at 37°C, appearance of blackening in the butt indicates H2S production.
18.104.22.168. Sugar fermentation test (Willis, 1977):
Suspected culture was inoculated to 1% peptone water tubes containing 2% bromocresol purple and 1% quantities of the…
Determining the Chemical Formula of Hydrated Copper (Ⅱ) Sulfate Using the Empirical Formula
In this experiment, the molecular formula of hydrated Copper (Ⅱ) Sulfate will be determined.
In order to determine the molecular formula, the empirical formula is needed which is the ratio of moles of one substance to another. In this experiment, it is the ratio of Copper (Ⅱ) Sulfate to water.
The empirical formula can be determined if the moles of the compared substances…
.1 Material Composition
The raw material mentioned above has to be taken into an appropriate ratio to compound the batch sample. Generally, to test the property change in the polymer by the influence of a filler/additive is done by processing several batches with different but gradual loading of the filler/additive.
Here, we have to test the properties of nano Calcium Carbonate in the polymer matrix of polypropylene. For this, 12 batches are prepared by using the different size of filler by…
