0.753-g sample of a chlorocarbon compound was analyzed by burning it in oxygen and collecting the evolved gases in a solution of NaOH. After neutralizing, the sample was treated with 25.74 mL of a 0.264 M AgNO3 solution. This precipitated the chloride (Cl-) out as AgCl and left an excess of AgNO3. The excess AgNO3 was titrated with 0.1 M KSCN and required 16.47 mL to reach the endpoint in a Volhard titration. Calculate the % w/w Cl– (35.45 g/mol) in the sample. Provide your answer to 2 places after the decimal point and without units. Reactions: Cl– + Ag+ → AgCl(s) Reaction 1 Ag+ + SCN– → AgSCN(s) Reaction 2 HINT: This is an example of a back-titration. Steps to success: First, calculate the TOTAL amount (in moles) of Ag+ added from the volume and molarity of the silver nitrate solution. Second, determine the EXCESS amount of Ag+ from the reaction with thiocyanate (Reaction 2 above). Third, calculate the…
A solution of oxalic acid dihydrate (H₂C₂O₄･2H₂O) with a known concentration of 0.400 M H₂C₂O₄･2H₂O is titrated with a 0.333 M NaO solution. How many L NaOH are required to reach the second equivalence point with a starting volume of 65.0 mL H₂C₂O₄･2H₂O, according to the following balanced chemical equation: H₂C₂O₄･2H₂O + 2NaOH → Na₂C₂O₄ + 4H₂O
Answer the following.
The zinc content of a 1.03 g ore sample was determined by dissolving the ore in HCl, which reacts with the zinc. The excess HCI is then neutralized with with NaOH. The reaction of HCl with Zn is shown. Zn(s) + 2 HCl(aq) ->> ZnCl₂ (aq) + H₂(g) The ore was dissolved in 150 mL of 0.600 M HCl, and the resulting solution was diluted to a total volume of 300 mL. A 20.0 mL aliquot of the final solution required 8.94 mL of 0.530 M NaOH to neutralize the excess HCl. What is the mass percentage (%w/w) of Zn in the ore sample? %w/w = % Zn
A quantitative analysis for ethanol, C2H60, is accomplished by a redox back titration. Ethanol is oxidized to acetic acid, C2H402, using excess dichromate, 3+ Cr207 2-, which is reduced to Cr3*. The excess dichromate is titrated with Fe2*, giving C and Fe+ as products. In a typical analysis, a 5.00-mL sample of a brandy is diluted to 500 mL in a volumetric flask. A 10.00-mL sample is taken and the ethanol is removed by distillation and collected in 50.00 mL of an 2- acidified solution of 0.0200 M K2Cr207. Titration of the unreacted Cr207 requires 21.48 mL of 0.1014 M Fe2*. Calculate the %w/v ethanol in the brandy. Which is the titrant in this problem? C2H402 Fe2+ C2H60 O Cr207 2-
Calculate the% of Ce (MA 140.115 g / mol) that contains a sample with a mass of 4.37 g that was dissolved and treated with an excess of iodate to precipitate it as Ce (I03) 4. The precipitate was washed, dried and calicoed, yielding 0.104 g of CeO2 (MM 172.114 g / mol). What is the% by weight of Ce in the sample?

Excess solid Ni(OH)2 was added to water and the resulting solution was allowed to stand for several days. The solution was then filtered to remove excess solid Ni(OH)2. A 0.250 L aliquot of the solution was then titrated with 10.54 mL of a standardized 0.000500 M HCl solution. What is the Ksp of Ni(OH)2?
Fe3+ in 50 mL solution, which is known to contain Fe3+, was precipitated as Fe(OH)3 and after necessary procedures, it was brought to constant weight as Fe2O3. Since the weight is found to be 0.3994 g, find the Fe3+ concentration in the solution in terms of molarity. (Fe: 55.85, O: 16.00 g / mol)

Mark and John, two vinegar enthusiasts, are each tasked to determine the acetic acid content of their respective vinegar concoctions by titration. First, a 1 M-labeled KOH solution was standardized against the KHP (MW = 204.22 g/mol) standard that is 99.4% pure. In the process, 0.540 g KHP was found to require 2.80 mL of the KOH solution to completely react up to the phenolphthalein endpoint. Then, Mark and John both prepared their samples by taking 10.0-mL aliquots of each vinegar and diluting them to 25.0 mL. Using the same titrant and indicator, Mark’s vinegar required 18.60 mL of the standardized titrant to reach the endpoint, while John’s vinegar required 16.50 mL of the same titrant to reach the same endpoint. Question: What is the acetic acid concentration of Mark’s and John’s vinegar in molarity given that the Concentration of KOH is 9386 M?
A sample contains MgCl2 (95.211 g/mol) and KCl (74.551 g/mol). A 6.6933-g sample was dissolved in enough H2O to make 250.0-mL solution. A 50.00-mL aliquot was treated with AgNO3 to precipitate the chlorides and after proper collection and drying gave a precipitate weighing 1.9620-g. Another 50.00-mL aliquot was tested for its Mg2+ content by precipitating it with NH4+ and PO43- giving an Mg2P2O7 (222.551 g/mol) precipitate weighing 0.5186 g with FW AgCl 143.32 g/mol. What is percent KCl in the sample?
