1-Vinyl-3-ethylimidazolium bromide (ViEt, purity ~99%) was purchased from Meryer Biochemical. 3-Sulfopropyl methacrylate potassium salt (SPMA, purity ~96%) was purchased from Aladdin. 3-(Acrylamidopropyl)trimethyl ammonium chloride (APTMA, 75 wt% in H2O) was purchased from Energy Chemical. 2...
Viscosities of potassium cellulose sulfate solution were measured in the presence of KCl, HCl, BaCl 2 , and cetyl trimethyl ammonium bromide. The reduced viscosity of an aqueous solution of potassium cellulose sulfate was shown to follow the general formula proposed by Fuoss and Strauss for the ...
To reduce the intense absorption of the samples measured, they have to be diluted with high-density polyethylene (HDPE) for the measurement in the THz range or potassium bromide (KBr) for the measurement in the IR range. Finally, the samples were pressed into surface-smooth pellets under ...
Does a precipitate form when aqueous solutions of sodium hydroxide and potassium chloride are mixed? If so, write the formula. Does a precipitate form when aqueous solutions of potassium hydroxide and magnesium bromide are mixed? If so, write ...
Write the balanced molecular, complete ionic, and net-ionic equations for the equation: Ammonium bromide (aq) + Potassium nitrate (aq) to Potassium bromide (aq) + Ammonium nitrate (aq) What is the net ionic equation for the react...
The molecular structure, chemical formula and the molecular weight of the selected chemicals are tabulated in Table 1. The experimental density values of deionized water, and aqueous TEAB and TEAI solutions are tabulated in Table 2. The trend in the value of densities measurement of aqueous TEAB...
The percent of increase in reduction power was calculated by using the following formula: Atest Increase in reduction power = 100 −1 Ablank where Atest is the optical density of the test solution and Ablank is the optical density of the blank solution. The assays were carried out in ...
Other examples of pore-formers include alkali metal salts such as lithium carbonate, sodium chloride, sodium bromide, potassium chloride, potassium sulfate, potassium phosphate, sodium acetate, sodium citrate, and the like. The pore-forming solids may also be polymers which are soluble in the envir...
