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 ...
although potassium acetate can be used in areas where chlorides are prohibited for environmental reasons. Potassium ions readily exchange for sodium counterions in smectites, and since they are larger and more weakly hydrated than sodium ions, clay swelling is inhibited[45,78]. Nitrogen-containing ...
The molecular weight of FEP and PTFE was calculated based on the data provided by Dupont (SSG method), using the formula30: LogMn¯=2.61−SSG0.06 (3) Calculation methods The density functional theory calculations were implemented in the Vienna ab initio Simulation Pack (VASP 6.2.1) code31...
3. A composition according to claim 2, in which the first anionic surfactant is sodium lauryl ether sulphate(n)EO (where n is 1). 4. A composition according to claim 1, in which the second anionic surfactant is a sulfosuccinate anionic surfactant having the general formula: R—(O—CH2...
1. 1.0 mol of magnesium acetate is dissolved in water. a) Write the formula for magnesium acetate. My answer: Mg(CH3COO)2 Process: I don't really know, that's just what I got. Writing out these things have never really been my strong point, along with everything else in regards to...
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...
2.5 g of sodium acetate (buffer) 2 g of acrylic acid EXAMPLE 5 Preparation of a Polymer Dispersion B The dispersion was prepared at 85° C. by adding feed 1 in the course of 120 minutes and feed 2 in the course of 150 minutes to an initially taken mixture heated beforehand for 15 mi...
Ecabet-sodium (4 g), methyl p-hydroxybenzoate (0.1 g) and propyl p-hydroxybenzoate (0.02 g) were dissolved under warming in purified water (80 ml). After sodium triphosphate (0.03 g., chemical formula: Na5P3O10) was added under stirring to the solution, the solution was adjusted to pH 7....
