You send a sample of rice to the lab for the determination of the total arsenic content. The analyst dissolves 525 mg of the rice in 5.0 mL of concentrated acid and then dilutes the solution to a final volume of 20.0 mL. When analyzed by ICP-MS, the solution concentration is found to be 20 µg L-1. What is the concentration of arsenic in the rice (in µg kg-1)?

The ethyl acetate concentration in an alcoholic solution was determined by diluting a 10.00-mL sample to 100.00 mL. A 19.00-mL portion of the diluted solution was refluxed with 40.00 mL of 0.04601 M KOH: CH3 СОО С2H; + ОН — СH3 COO + C2H; ОН After cooling, the excess OH was back-titrated with 3.02 mL of 0.05056 M H2 SO4. Calculate the amount of ethyl acetate (88.11 g/mol) in the original sample in grams. Amount of ethyl acetate =
2+ as (6) A sample of an ore was analyzed for Cu* follows. A 1.25 g sample of the ore was dissolved in acid and diluted to volume in a 250 mL volumetric flask. A 20 mL portion of the resulting solution was transferred by pipet to a 50 ml volumetric flask and diluted to volume. An analysis showed that the concentration of 2+ Cu* in the final solution was 4.62 ppm. What is the weight percent of Cu in the original ore?
A set of five solutions are prepared by delivering 10 mL of unknown sample and increasing volumes of standard (0, 5, 10, 15, and 20 mL) into 50-mL volumetric flasks. Analytical reagents are then added and the flasks are diluted to volume. The x-intercept of the best-fit line is -5.63 mM. What is the concentration of the unknown? w 2

Formulate a hypothesis regarding the solubility of aspirin at different pH. The experiment A) Three teaspoons of water (approx. 15 ml) were added to one tablet said to contain 300 mg of aspirin. Fizzing was observed. Most of the tablet dissolved, but there were some solid particles. By heating the mug in a microwave for 10 second increments until the water came to the boil (approx. 3x), all of the solid partides dissolved. The solution was left to cool to room temperature and then placed in a fridge and NOTHING HAPPENED. Try this yourself if you can spare two aspirin tablets, your results might look different. Questions to ask: 1. What might the fizzing bubbles be? 2. Can you give a chemical explanation? 3. Can you write a chemical reaction equation with aspirin reacting with something to give a gas and aspirin in another form? 4. What might be the formulation (what the manufacturer mixes with aspirin in making the tablet) "trick" for aspirin to improve solubility? 5. How does this…
A mixture containing only KCl and NaBr is analyzed by the Mohr method. A 0.2125-g sample is dissolved in 25 mL of water and titrated to the Ag2CrO4 endpoint, requiring 25.63 mL of 0.1110 M AgNO3. A blank titration requires 1.15 mL of titrant to reach the same end point. Report the %w/w KCl and NaBr in the sample. KCl = 74.551 NaBr = 102.89

Example You determine the acetic acid content in vinegar by titrating with a standard (known concentration) solution of NaOH to a phenolphthalein endpoint. 5.023± 0.003 g sample of vinegar is weighed. The NaOH must be standardized by KHP and 3 such titrations gave molarities of 0.1167, 0.1163 and 0.1164 M. A volume of 36.78 ± 0.03mL NaOH is used to titrate the sample. What is the percent acetic acid in the vinegar and what is the overall uncertainty?Answer: 5.12% ± 0.01%
