A 25.863 g sample of aqueous waste leaving a fertilizer manufacturer contains ammonia. The sample is diluted with 74.612 g of water. A 14.159 g aliquot of this solution is then titrated with 0.1059 M HCl. It required 31.31 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.

A 10.00-g sample that contains an analyte is transferred to a 250-mL volumetric flask and diluted to volume. When a 10.00 mL aliquot of the resulting solution is diluted to 25 ml it gives a signal of 0.235 (arbitrary units). A second 10.00 mL portion of the solution is spiked with 10.00 mL of a 1.00-ppm standard solution of the analyze and diluted to 25.00 mL. The signal for the spiked sample is 0.502. Calculate the weight percent of analyte...

A 1.00 g pill contains morphine (M = 285.34), a monobasic compound whose conjugate acid has pKa = 8.21, in addition to an unknown amount of inert material. To analyze the morphine content of the pill, it is dissolved in 50.0 mL 0.1000 M aqueous HCl and the unreacted acid in the resulting solution back-titrated with 0.1000 M NaOH. Which of the following statements about this experiment are correct? I. If the pill contains only morphine, the titration will require...
