Amino acids are an important group of compounds. At low pH, both the carboxylic acid group (CO2H) and the amine group (NHR) are protonated. However, as the pH of the solution increases (say, by adding base), the carboxylic acid proton is removed, usually at a pH between 2 and 3. In a middle range of pHs, therefore, the amine group is protonated, but the carboxylic acid group has lost the proton. (This is called a zwitterion.) At more basic pH values, the amine proton is dissociated. What is the pH of a 0.20 M solution of alanine hydrochloride, [NH3CHCH3CO2H]Cl?
Explain why an acid-base indicator changes color over a range of pH values rather than at a specific pH.
A mysterious white powder is found at a crime scene. A simplechemical analysis concludes that the powder is a mixtureof sugar and morphine 1C17H19NO32, a weak base similar toammonia. The crime lab takes 10.00 mg of the mysteriouswhite powder, dissolves it in 100.00 mL water, and titrates itto the equivalence point with 2.84 mL of a standard 0.0100M HCl solution. What is the percentage of morphine in thewhite powder?(a) 8.10%(b) 17.3%(c) 32.6%(d) 49.7%(e) 81.0%
Assuming only the neutral form of the compound significantly "bioconcentrates" in fish, Estimate the equilibrium concentration (ug chemical/kg wet fish) of the acid pentachlorophenol (PCP) in a rainbow trout swimming in water (pH =7) having a total concentration of 10 ug/L PCP (both neutral and negatively charged forms. The log Kow for the neutral form of pentachlorophenol is 5.0 and the pKa is 5.

In the year 1980, countries near the United States experienced an increase in acid precipi- tation. During this same year, the United States had an increase in the burning of fossil fu- els to power homes and vehicles. Which statement best describes how these two occurrences are related? The United States' emissions of sulfur dioxide and nitrogen dioxide increased as a result of a decrease in the burning of fossil fuels to power homes and vehicles, and wind pat- terns caused these emissions to travel, leading to the formation of acid precipitation in other areas. The United States' emissions of sulfur dioxide and nitrogen dioxide increased as a result of an increase in the burning of fossil fuels to power homes and vehicles, and wind pat- terns caused these emissions to travel, leading to the formation of acid precipitation in other areas. The United States' emissions of sulfur dioxide and nitrogen dioxide decreased as a re- sult of an increase in the burning of fossil fuels to power…
There is a buffer system in blood H2PO4- - HPO42- that helps keep the blood pH at 7.40. (KaH2PO4- = 6.2 x 10-8) . (a) Calculate the [H2PO4-] I [HPO42-] ratio at the normal pH of blood. (b) What percentage of the HPO42- ions are converted to H2PO4- when the pH is 7.00? (c) What percentage of the H2PO4-ions are converted to HPO42- when the pH is 8.00?
Which one of the following statements is correct concerning the acetic acid in vinegar and neutralizing capacity of antacid experiments? O Starch can be used as a binder in antacid tablets. O The antacid tablet should be dissolved in a stoichiometric amount of HCI solution. O An antacid tablet is dissolved in H₂O first then titrated with standardized NaOH solution. O One of the active ingredients in most commercial antacid tablets is Ca(OH)2. O The titration flask should be rinsed with vinegar solution before titration with NaOH solution.
