- One litre of a saturated aqueous solution of Ag2SO4 (MW = 311.79 g mol- 1) at 25 °C is evaporated to dryness. 4.844 g of Ag2SO4 residue was produced. What is the solubility product (Ksp)?Hexanoic acid was added to an immiscible biphasic solvent sysem, water and CCl4 at 20.0OC and the equilibrium concentrations of hexanoic acid were determined to be 3.66 g/L in H2O and 67.0 g/L in CCl4. Caluclate the distrubution coeffiecent (D1) of hexanoic acid in CCl4 with respect to water.A reaction for converting ketones to lactones, called theBaeyer–Villiger reaction, is used in the manufacture of plastics and pharmaceuticals.3-Chloroperbenzoic acid is shock-sensitive, however,and prone to explode. Also, 3-chlorobenzoic acid isa waste product. An alternative process being developeduses hydrogen peroxide and a catalyst consisting of tindeposited within a solid support. The catalyst is readilyrecovered from the reaction mixture. (a) What wouldyou expect to be the other product of oxidation of theketone to lactone by hydrogen peroxide? (b) What principlesof green chemistry are addressed by use of the proposedprocess?

Although the CO2 concentra?on in the atmosphere raises at a drama?c speed, point sources are probably the easier sources for a PtX process. Iden?fy 3 possible point sources, explain why CO2 is formed and what challenges each of the three CO2 streams presents8.00mL aqueous suspension of elemental selenium is treated with 24.00mL ammonia 0.045M AgNO3 The reaction is as follows: 6Ag (NH3) 2 ++ 3Se (s) + 3H2O → 2Ag2Se (s) + Ag2SeO3 (s) + 6NH4 + After this reaction is completed, nitric acid is added to dissolve Ag2SeO3. However, Ag2Se does not dissolve during this time. Ag + consisting of dissolved Ag2SeO3 and the excess of the reagent requires 13.43mL 0.01294M KSCN in a Volhard titration.

What is the residues concentration?A(n) ___________ property describes the behavior of asubstance when it reacts or combines with anothersubstance.It is required to know the concentration of an aqueous solution of H2SO4 that appeared in the laboratoryChemistry III and it's unlabeled. To this end, a student of analytical chemistry carried out the followingProcedure: He took 5.00 mL of a fresh and standardized solution of 0.525M NaOH and brought them to a250.0 mL balloon to be completed with distilled water. Subsequently, he poured 15.00 mL of the solutionH2SO4 of unknown concentration in an Erlenmeyer flask and added 2 drops of phenolphthalein.Using a burette filled with the last NaOH solution, he noticed that when adding 39.40 mL of the hydroxidethe Erlenmeyer solution reached a faint but permanent pink. With the above dataDetermine the concentration and pH of the H2SO4 solution.

However, a safety re-view finds that the waste stream could meet a small stream of animmiscible organic compound, which could form a flammable vapor in air at 40.°C. The maximum temperature of the causticsoda and the waste stream is 31°C. Could the temperature in-crease due to the heat of neutralization cause the vapor to ex-plode? Assume the specific heat capacity of each solution is 4.184 J/gK.
