A commercial research organization is planning to develop a sensor to detect methyl parathion that may be injected into a water supply by terrorists. The LD50 for methyl parathion is reported to be as low as 6 mg ・ kg−1 for rats. They are assuming a safety factor of 1 × 105 and a volume of liquid ingested equal to a cup of coffee (about 250 mL) in the design of the instrument. What concentration (in mg ・ L−1) must their instrument be able to detect? Using Equation 6–10, the concentration you have calculated, the ingestion rate of 250 mL, an exposure frequency of one day, and exposure duration of one day, an adult malebody weight, and an averaging time of 1 day, estimate the hazard index. The RfD for methyl parathion is 2.5 × 10−4 mg ・ kg−1 ・ d−1 .
A 10.00 mL aliquot of vinegar (acetic acid, CH3COOH - 60.08 g/mol) was diluted in a 100.00 mL volumetric flask and made up with distilled water. An aliquot of 10.00 ml was pipetted into an erlenmeyer flask, to which two drops of phenolphthalein were added. This solution was then titrated with 0.1006 mol/L NaOH. i) Considering that the volume of NaOH consumed was 8.28 mL, what is the molar concentration of acid in dilute solution? ii) What is the acidity percentage of vinegar? iii) Whereas the expected concentration of the acetic acid solution was equal to 0.0830 mol/L, calculate the volume of NaOH needed to reach the point of equivalence. iv) Based on the volume calculated in the previous item and the volume indicated in item (i), calculate the titration error.
Federal regulations set an upper limit of 50 parts per million(ppm) of NH3 in the air in a work environment [that is, 50molecules of NH31g2 for every million molecules in the air].Air from a manufacturing operation was drawn through asolution containing 1.00 * 102 mL of 0.0105 M HCl. TheNH3 reacts with HCl according to: NH3(aq) + HCl(aq)-------->NH4Cl(aq) After drawing air through the acid solution for 10.0 min at arate of 10.0 L/min, the acid was titrated. The remaining acidneeded 13.1 mL of 0.0588 M NaOH to reach the equivalencepoint. (a) How many grams of NH3 were drawn into theacid solution? (b) How many ppm of NH3 were in the air?(Air has a density of 1.20 g/L and an average molar mass of29.0 g/mol under the conditions of the experiment.) (c) Isthis manufacturer in compliance with regulations?

A student carried out an experiment trying to prepare tetra-methyl-ammonium tri-iodide.The student weighed 1.13 g tetra-methyl-ammonium iodide into a beaker containing 25 mL ethanol, and then added 1.57 g of iodine. The mixture was heated gently, whilst stirring, on a hotplate until tetra-methyl-ammonium iodide, a white powder, was completely dissolved. After the mixture was allowed to cool down to room temperature, the mixture was further cooled on ice. After filtration on a Buechner funnel, washing with diethyl ether and leaving it under vacuum suction for a couple of minutes, the student recovered the product and weighed it. The mass of the obtained tetra-methyl-ammonium triiodide was 1.62 g.What is the yield of the reaction in percent [%]? For the calculation, assume that the product is completely dry and pure, so there are no impurities like side-products, unreacted educts, or solvent residues.

Most analytical machines used in science can either measure absorbance of light, like the spectrophotometers used in BioZ 151 and 152 labs, or can measure change in electrical conductance. In order to convert things like absorbance values into concentration data, a linear regression is used. In order to determine nitrite concentration in water samples, nitrite is reacted with several chemicals to produce a purple color. The absorbance of the solution is measured from known amounts of nitrite to produce a standard curve to analyze samples. Use the data in the provided table, or from the linked spreadsheet (Links to an external site.)to make a graph and perform a linear regression using treadline. mg/L NO3- Absorbance 0 0 0.1 0.183 0.3 0.542 0.5 0.914 0.7 1.298 1 1.61 In order for this to work, samples must be diluted prior to measurement so that the concentration falls within the range of the standard curve. If a sample underwent a 87 dilution, and produce an…
A solid sample containing chloride ion is analyzed by argentimetric titration to find the percentage chloride by mass. The procedure involves the preparation of a solution made from primary standard sodium chloride (molar mass = 58.443 g mol-1). Aliquots of NaCl solution will be titrated with silver nitrate solution to accurately determine the AgNO3 concentration. The standardized silver nitrate will be used to titrate aliquots of unknown chloride solution, thus allowing for the determination of the percentage chloride in the original solid sample. To detect the endpoint of the titration the adsorption indicator dichlorofluorescein is used. Please solve for the highlighted portions.
