What is the difference between an aliquot factor and a dilution factor? What is the difference between goethite, hematite and ferrihydrite? What is the difference between a saturated and unsaturated fat? What is the difference between a metal and a non-metal?
What is the solubility of PbCl2 in 0.50 M NaCl solution, in g/L? MW of PbCl2 = 278 g/mol. What is the molar solubility of lead (ii) chloride in 0.100 m KCl? What is the solubility of a salt x at 25 degree C, if the saturated solution of the salt contain 0.28 g in ...
Preparation A mixture of formaldehyde (0.32g), diethyl malonate (0.22g), and potassium carbonate (0.0276g) was dissolved in 10mL of water. The reaction was carried out at 30°C for 6 hours. After the reaction, the mixture was diluted with saturated sodium chloride solution, extracted with et...
Which solution is more concentrated? 10% NAOH or 1 m NAOH? At which temperature do solutions chloride and potassium chloride have the same solubility? What does molarity measure the concentration of? If a saturated solution of Sr(OH)2 at 20 deg C is shown to contain 32 mg/1000 mL of Sr...
What is ammoniacal brine? Ammoniacal brine isa commercially important chemical used in the ammonia soda process. It is formed by taking saturated sodium chloride and bubbling through ammonia gas. The ammoniacal brine then can be used to to make sodium carbonate (soda ash) and other chemicals. ...
Tonometer tips are frequently cleaned with a wipe saturated in 70% isopropyl alcohol or soaked for at least 5 minutes in a 70% solution (the method recommended by the US Center for Disease Control) and applied to the corneal surface. If this is done before the alcohol has completely dried,...
Chlorides in the pore solution were defined as the free water content of each paste sample (i.e., the difference in weight between its saturated surface dry condition and after drying by solvent exchange) multiplied by the concentration of the exposure solution at equilibrium. The quantity of ...
Saturated Solution--At this point, the concentration of the solute in solution is the maximum possible under the existing conditions (temperature and pressure). A solution is saturated when no more solute can be dissolved at the current temperature. A saturated solution is one in which the dissol...
Another peculiarity is that, in water, polyvinyl alcohol never retains its original powdery nature as the excess sodium chloride does in a saturated salt solution. In conclusion, we can say that (1) the long time taken by polyvinyl alcohol for dissolution. (2) the absence of a saturation ...
