A student determined the chloride content of a commercial salt by using the Mohr method. A 0.6971 -g sample of the salt was dissolved in distilled water and diluted to a final volume of 250. mL. A 25.-mL aliquot of the analyte solution was then titrated against a standard 0.0333 M AgNO3(aq) solution to the chromate end-point. A blank-corrected volume of 25.30 mL was recorded. Calculate the percent chloride in the sample.

Question 2 (2 points) A 3.2100-g sample of a salt was analyzed for its chloride content as follows: the entire sample was dissolved with distilled water in a 500.0-ml volumetric flask. A 100.00-mL aliquot of the solution required 24.89-mL of a 0.03769 M silver nitrate solution to reach equivalence. A blank correction was not required. Calculate the % (w/w) chloride in the sample. The net-ionic equation for the reaction is Ag*(aq) + CI (aq) - AgCl(s). Provide your answer to...

Chloride in a water sample can be determined indirectly by
atomic absorption spectrometry by precipitating chloride as AgCl(s)
with a measured amount of AgNO3 that is excess of the chloride
content of the sample. The AgNO3 is added and the sample is
centrifuged. The remaining Ag+ in the solution (supernatant) is
quantified and the chloride is measured by assuming that chloride
was quantitatively precipitated.

A mixture only contains KCl and NaBr is analysed using Mohr method. A sample of this mixture weighing 0.3172 g is dissolved in 50.00 mL distilled water and titrated to an end-point 36.85 mL of 0.1120 M AgNO3 solution. The blank titration required 0.71 mL to reach the same end-point. Calculate the percentage (w/w) of KCl and NaBr each in the same sample. [RMM: KCl = 74.6, NaBr = 102.9]

Question 10 (2 points) A 13.9800-g sample of a salt was analyzed for its iron content as follows: the entire sample was dissolved and diluted to 400.0 mL in a volumetric flask. A 80.00-ml aliquot of the solution required 25.38-mL of a 0.04119 M potassium permanganate solution to reach equivalence. A blank correction of 0.50 mL was required. Calculate the %(w/w) Fe in the sample. The net-ionic equation for the reaction is MnO4 (aq) + 8H+ (aq) + 5Fe2+(aq) -...

A student followed the procedure of this experimer 3. commercial bleaching solution that was found in the basement of an abandoned house. The student diluted 50.00 mL of the commercial bleaching solution to 250 mL in a volumetric flask, and titrated a 20-mL aliquot of the diluted bleaching solution. The titration required 35.46 mL of 0.1052M NaS, O, solution. A faded price label on the gallon bottle read $0.79. The density of the bleaching solution...

The zinc content of a 1.23 g ore sample was determined by dissolving the ore in HCI, which reacts with the zinc, and then neutralizing excess HCl with NaOH. The reaction of HCI with Zn is shown below. Zn(s)-2HCl(aq) → ZnCl2(aq)-H,(g) The ore was dissolved in 150 mL of 0.600 M HCI, and the resulting solution was diluted to a total volume of 300 mL. A 20.0 mL aliquot of the final solution required 9.19 mL of 0.529 M NaOH...
