Experiments involving chemical reactions can be performed using simple household ingredients and products such as baking soda and vinegar.
When baking soda (sodium hydrogen carbonate) reacts with ethanoic acid which is found in vinegar in a 1:1 ration, the reaction will produce three different products which are water, carbon dioxide and Sodium acetate.
The reaction is:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
In the experiment, the quantitative relationship between the two reagents which is the…
In 2003, li Also as much coworkers70 synthesized 3-arylimidazo[1,2-a]pyrimidines from imidazo[1,2-a]pyrimidine a unsubstituted heterocycle In those 3-position Toward performing regulate arylation response with aryl bromides. Those creator utilized Pd(OAc)2 (2 mol %) Concerning illustration An catalyst, PPh3 (4 mol %) Likewise An ligand, Also Cs2CO3 (2 equiv) Concerning illustration An base, those response advanced proficiently in 1,4-dioxane during 100 °C. Those yield might have been attained in…
percentage amounts of ethanol in them; Listerine, Terra Fresca Wine and the last is a mixture of ethanol and water that was made by me. The three different methods compared are the redox titration method which involves the oxidation of ethanol to ethanoic acid and then titrating the residue with sodium thiosulfate, which would then be used to calculate the number of moles of ethanol present in the original sample. The method of distillation involves heating the samples to the boiling point of…

Lecithins vary greatly in their physical form, from viscous semiliquids to powders, depending upon the free fatty acid content. They may also vary in color from brown to light yellow, depending upon whether they are bleached or unbleached or on the degree of purity. When they are exposed to air, rapid oxidation occurs, also resulting in a dark yellow or brown…
nature, it was possible to utilize it as an acid catalyst for the dehydration reaction.4 The use of Montmorillonite K10 is an excellent example of green chemistry as it not only shows the use of catalysts to increase efficiency but also displays a less hazardous form of chemical synthesis.
The cyclohexene collected from the first experiment served as the starting material for the next reaction of the cycle in which, hydrogen peroxide (H2O2) and hydrobromic acid (HBr) were combined to generate…

Posttreatment of anaerobically treated DWW by aerobic activated sludge using SBR and membrane UF was investigated. The aim of this study was to reduce the organic loading (COD and BOD), nutrients (TKN, NO2, NO3 and TP) and total suspended solids (TSS) of anaerobically treated DWW effluent first by the activated sludge system using SBR and further treated by ceramic tubular membrane UF separately to investigate the possibility of the reusing the effluent for different purposes depending on the…
RESULTS AND DISCUSSION
4.1 Extraction using Different Solvents
The grounded Ixora coccinea and Beta vulgaris plant samples were extracted using the following solvents: Acetone, ethanol, methanol and ethyl acetate. The absorbance was noted to select the best choice of solvent for extraction.
Acetone, ethanol and methanol showed higher values. But, the dye extracted from acetone and ethanol did not fix to the fabric properly. So, methanol was selected as solvent for…
In this study, reverse micellar extraction of asparaginase model system was carried out using CTAB/Iso-octane/hexanol/butanol system to optimize the forward and back extraction efficiency. By using Taguchi’s orthogonal array (OA), maximum forward extraction efficiency of 55.0%, 61.0% and 54% was achieved with an aqueous phase pH of 11.0, 150mM CTAB/Iso-octane and 0.1 M NaCl, respectively. Similarly, Taguchi’s orthogonal array (OA) was applied to optimize the pH of stripping phase,…
