A solution contains formic and tartaric acids. A 25.00 mL aliquot portion is treated with 50.00 mL of a 0.1663 mol/L solution of cerium(IV) in 12 mol/L sulfuric acid; after boiling for one hour, it is cooled to room temperature and the excess cerium(IV) is titrated with 8.24 mL of iron(II) 0.1108 mol/L. Under these conditions all organic acids are oxidized to carbon dioxide. Another 25.00 mL aliquot portion of the acid solution is treated with 20.00 mL of 0.2383 mol/L cerium(IV) in 4 mol/L perchloric acid and heated at 50°C for 20 minutes. The solution was then titrated with 14.65 mL of 0.1012 molL oxalic acid. Under these conditions all organic acids are oxidized to formic acid. (a) Calculate the concentration of formic acid in g/L (b) Calculate the concentration of tartaric acid in g/L

An analytical chemist is titrating 234.9 mL of a 0.5100M solution of trimethylamine ((CH3)N) with a 0.5700M solution of HNO3. The pK, of trimethylamine is 4.19. Calculate the pH of the base solution after the chemist has added 251.7 mL of the HNO3 solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO3 solution added. Round your answer to 2 decimal places. pH = -0 X $
A compound is known to have a free amino group with a pKa of 8.6, and one other ionizible group with a pKa between 5 and 7. To 90mL of a 0.150M solution of this compound at pH 7.80 was added 35 mL of a solution of 0.18 M HCl. The pH changed to 6.40. What is the pKa of the second ionizable group?
A 0.500 g sample consisting of Na2CO3, NaHCO3, and inert materials was dissolved in sufficient water to give 250.0 mL of solution. A 25.00 mL aliquot of this solution was boiled with 50.00 mL of 0.01255 M HCI. Titration of the excess HCI to a phenolphthalein endpoint required 2.34 ml of 0.01063 M NaOH. The carbonate species in the second 25.00 mL aliquot was precipitated with an excess of BaCl2 and treated with 25.00 mL of the NaOH. Titration of the excess base required 7.63 mL of the standard acid. Calculate % Na,CO3 and NaHCO3 in the sample.

Phenylamine is an aromatic amine that is used in the manufacture of dyes. When absorbed through the skin itcauses the Fe+2 in hemoglobin to become oxidized into Fe+3, resulting in the formation of methemoglobin whichcannot bind to or transport oxygen. Phenylamine is soluble in water and acts as a weak base.C6H5NH2 (aq) + H2O (ℓ) ⇋ C6H5NH3+ (aq) + OH- (aq)a. When you measure the concentrations of the ionized substances you find them to be:[C6H5NH2] = 0.234 mol/L [C6H5NH3+] = 2.8 x 10-5 mol/L [OH-]= 2.8 x 10-5 mol/LIf the Kb is 4.27 x 10-10, is the reaction at equilibrium? If not, which direction does it need to move (rightor left) to reach equilibrium? Explain. b. At equilibrium the concentrations of the ionized substances are:[C6H5NH2] = 0.0537 mol/L [C6H5NH3+] = 4.79 x 10-6 mol/L [OH-]= 4.79 x 10-6 mol/LIf this reaction is taking place in a 2.0L container, and 1.5 moles of phenylamine were added to thereaction, what will the new concentrations of the three ionic species be when…
