if tap water was used instead of deionized water, how would the molar solubility of calcium hydroxide be affected? Qualitatively how is the molar solubility of Ca(OH)2 affected by the presence of CaCl2 in the solution? 1) If the solubility of calcium hydroxide is...
Calculate the molar solubility of this compound. The K_{SP} of nickel(II) hydroxide, Ni(OH)_2, is 5.84 times 10^{-16}. Calculate the molar solubility of this compound. The Ksp of calcium hydroxide, Ca(OH)2, is 5.02 x 10-6. Calculate...
2.2. Fabrication of EPL-crosslinked starch nanofibers The oxidized starch nanofibers were prepared as described in our previous report [27]. In this experiment, the molar ratio of NaIO4 to the anhydroglucose units of starch was 30%, and the actual oxidation degree determined by hydroxylamine hydro...
Alkali-silica reaction (ASR) is one of the important concrete durability issues worldwide [1]. The reaction occurs between the reactive silica in concrete aggregates and alkali hydroxide together with calcium from the concrete pore solution, leading to the formation of ASR products with ensuing exp...
where r is the corrosion rate (mg·cm−2·d−1), P is standard atmospheric pressure (Pa), V is volume of H2 (mL), R is 8.314 J/(mol·K), T is the temperature (K), M is the molar mass (g/mol), A is the original surface area (cm2), t is the exposure time (day...
of calcium salt, and proteins with a concentration corresponding to 0.3 g of protein to 1 g of calcium salt were added to the Na2SiO3solution. The higher mass of proteins compared to amino acids was chosen because of the higher molar mass of the proteins compared to the amino acids....
Molar mass is the mass of one mole of a substance. We determine the molar masses from values on the periodic table. Answer and Explanation: Before we can sum all of the molar mass of the elements in acetic acid we need the chemical formula of acetic acid. Acetic acid's chemical formula...
solution ratio of ~ 1:1000 g dry wt mL−1. The initial C:(Mn or Fe) molar ratios are derived from the DOC concentration of the leachate—equivalent to the total C concentration within error—and the initial solid-phase Mn or Fe concentration. The pH of the suspensions was maintained ...
Colloidal silicon dioxide (SiO2AP) showed a high LOI (9%), as this material has a high moisture adsorption capacity59. Although storage conditions were guaranteed, the sample adsorbed moisture during handling. The LOI determined by thermogravimetric analysis (TG) indicated that the mass loss occurs...
In this work, four natural gas (NG) samples were treated to remove CO2 and H2S using 10–50% Di-Ethanolamine (DEA) solutions mixed with 5% w/w 0.1 M calcium hydroxide. The treatment process gave increased acid gas removal at increased DEA concentrations. Based on the simulation results, ...
