Rei and Akari, two vinegar enthusiasts, are each tasked to determine the aceticacid content of their respective vinegar concoctions by titration. First, a 1M-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 require2.80 mL of the KOH solution to completely react up to the phenolphthaleinendpoint. Then, Rei and Akari both prepared their samples by taking 10.0-mLaliquots of each vinegar and diluting them to 25.0 mL. Using the same titrant andindicator, Rei's vinegar required 18.60 mL of the standardized titrant to reach theendpoint, while Akari's vinegar required 16.50 mL of the same titrant to reach thesame endpoint.

If the legal minimum acetic acid content in vinegar is 1.50M, which of the two vinegar enthusiasts- Rei, Akari, or BOTH, are allowed to sell their vinegars for business?

Rei and Akari, 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, Rei and Akari 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, Rei's vinegar required 18.60 mL of the standardized titrant to reach the
endpoint, while Akari's vinegar required 16.50 mL of the same titrant to reach the
same endpoint.

A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 303 mg of oxalic acid, a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250mL of distilled water. The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 104.5 mL of sodium hydroxidesolution. Calculate the molarity of the student's sodium hydroxide solution. Round your answer to 3 significant digits.
As part of a soil analysis on a plot of land, a scientist wants to determine the ammonium content using gravimetric analysis with sodium tetraphenylborate, Na+B(C6H5)4−. Unfortunately, the amount of potassium, which also precipitates with sodium tetraphenylborate, is non‑negligible and must be accounted for in the analysis. Assume that all potassium in the soil is present as K2CO3 and all ammonium is present as NH4Cl. A 5.095 g soil sample was dissolved to give 0.500 L of solution. A 150.0 mL aliquot was acidified and excess sodium tetraphenylborate was added to precipitate both K+ and NH4+ ions completely. B(C6H5)4-+K+⟶KB(C6H5)4(s) B(C6H5)4-+NH4+⟶NH4B(C6H5)4(s) The resulting precipitate amounted to 0.269 g. A new 300.0 mL aliquot of the original solution was made alkaline and heated to remove all of the NH4+ as NH3. The resulting solution was then acidified, and excess sodium tetraphenylborate was added to give 0.129 g of precipitate. Find the mass percentages of NH4Cl and…
