A 0.4108-g sample of primary-standard Na2 CO3 was treated with 46.50 mL of dilute perchloric acid. The solution was boiled to remove CO2, following which the excess HClO4 was back-titrated with 9.90 mL of dilute NaOH. In a separate experiment, it was established that 26.90 mL of the HC1O4 neutralized the NaOH in a 24.00-mL portion. Calculate the molarities of the HC104 and NaOH. Molarity of the HC1O4 = M Molarity of the NaOH = M

A chemistry graduate student is given 125. mL of a 1.20M dimethylamine ((CH3)₂NH) solution. Dimethylamine is a weak base with K₁=5.4 × 10-4. What mass of (CH3)NH₂Br should the student dissolve in the (CH3) NH solution to turn it into a buffer with 2 pH = 11.05? You may assume that the volume of the solution doesn't change when the (CH3)NH₂Br is dissolved in it. Be sure your answer has a 2 unit symbol, and round it to 2 significant digits.
7.7 g of citric acid (MM = 192.1 g/mol) can be titrated with NaOH according to the following balanced chemical equation. H3C6H5O7 (aq) + NaOH(aq) → H2O(l) + Na H2C6H5O7(aq) what would the curve for the titration of the neutralization of the three hydrogens of this acid with NaOH look like?
A pipette is used to add 41 mL of 0.2 M Pb(NO3)2 to a 268.0 mL solution of 0.2 M NaF. Determine the equilibrium concentration of Pb2+(aq) in the final solution. Ksp(PbF2)=3.6E-8Include at least 3 significant figures in your answer.
An alkaline earth hydroxide, M(OH)2, was taken to lab for analysis. The unknown powder was poured into a flask and swirled in room temperature DI water until a saturated solution formed. This solution was then slowly filtered to remove the undissolved solid hydroxide. 11.9 mL of this saturated solution was titrated with 0.148 M HCI (ag). Endpoint required 15.6 mL of the HCl (ag) solution. Calculate the Kan for this alkaline earth hydroxide.
7.) A saturated solution of M(OH)2 is prepared and then filtered to remove any undissolved solid M(OH)2. 15.0 mL of the filtered, saturated solution was titrated with a 0.035 M HCI solution. Examination of the pH titration curve indicated that it took 11.60 mL of the HCl solution to reach the equivalence point. What is the [M2+] in the saturated solution? [M2+] =
(a) Lactic acid, (CH3CH(OH)COOH) is a common biomolecule which can accumulate in muscles during intense exercise.

A solution contains a mixture of Na2CO3 and NaHCO3. Titration of a 30.0 mL portion of the solution to a phenolphthalein end point requires 12.16 mL of 0.306 M HCl. Another 30.0 mL portion of the solution requires 42.76 mL of the 0.306 M HCl when titrated to a bromocresol green end point. Calculate the molarity of the NaHCO3 in the original solution. Please keep your answer in normal number to three decimal places (x.xxx).
