The amount of aspirin (C_9H_7O_4H, molar mass = 180.15 g/mole) in a commercial tablet was determined by titration with sodium hydroxide. What mass of aspirin was in a tablet if 15.00 mL of 0.2000 M NaOH solution were needed to titrate the tablet dissolved in 30 mL of water? Show all calculations. Would more or less of NaOH titrant in problem 6 be required if the amount of water initially added to the Erlenmeyer flask with the product to be...

A 0.1019 - g portion of an aspirin tablet was dissolved in sufficient water to prepare 1.000 liter of solution. A pipet was used to transfer 10 mL of the solution to a 100 - mL volumetric flask. A 2 - mL portion of 4 M sodium hydroxide solution was added to the flask, and the resulting solution was diluted to the mark with water. The fluorescence of the diluted sample solution was found, by the working curve method, to...

A student is given an antacid tablet that weighed 5.6832 g. The tablet was crushed and 4.3628 g of he antacid was added to 200 mL fo simulated stomah acid. This was allowed to react and the filtered. It was found that 25 mL fo this partially neutralized stomach acid required 8.5 mL of a NaOH solution to titrate it to a methyl red endpoint. If it took 25.5 mL of this NaOH solution to neutralize 25 mL of the...

A 100 mg vitamin C tablet weighed 1.573 g. A student crushed the tablet and transferred 0.117 g of the crushed powder into a 100 mL volumetric flask, dissolved the powder in ~30 mL DI water, then filled the flask to the calibration line with DI water and mixed well to create Solution 1. The student then transferred 22.1 mL of Solution 1 into a 100 mL volumetric flask and diluted to the calibration line with DI water to create...
