Ibuprofen is a weak acid with a pK, of 4.9 (structure is shown with the ionizable hydrogen marked with a star). Ibuprofen is absorbed through the stomach and the small intestine. In these tissues, absorption is a function of polarity. Charged and very polar molecules are absorbed slowly; neutral hydrophobic molecules absorb quickly. If the stomach pH is about 1.5 and the small intestine pH is about 6, whem (and why) will more ibuprofen be absorbed into the bloodstream? OH* HgC HC CH ECH H3C „CH2 CH ČH3 More ibuprofen will be absorbed in the small intestine because it will be uncharged due to the pH being greater than the pK. O More ibuprofen will be absorbed in the stomach because it will be charged due to the pH being lower than the pK. O More ibuprofen will be absorbed in the small intestine because it will be charged due to the pH being greater than the pK. More ibuprofen will be absorbed in the stomach because it will be uncharged due to the pH being lower than the pk. Ibuprofen will be absorbed equally well in both the stomach and small intestine.

Phenylamine is an aromatic amine that is used in the manufacture of dyes. When absorbed through the skin itcauses the Fe+2 in hemoglobin to become oxidized into Fe+3, resulting in the formation of methemoglobin whichcannot bind to or transport oxygen. Phenylamine is soluble in water and acts as a weak base.C6H5NH2 (aq) + H2O (ℓ) ⇋ C6H5NH3+ (aq) + OH- (aq)a. When you measure the concentrations of the ionized substances you find them to be:[C6H5NH2] = 0.234 mol/L [C6H5NH3+] = 2.8 x 10-5 mol/L [OH-]= 2.8 x 10-5 mol/LIf the Kb is 4.27 x 10-10, is the reaction at equilibrium? If not, which direction does it need to move (rightor left) to reach equilibrium? Explain. b. At equilibrium the concentrations of the ionized substances are:[C6H5NH2] = 0.0537 mol/L [C6H5NH3+] = 4.79 x 10-6 mol/L [OH-]= 4.79 x 10-6 mol/LIf this reaction is taking place in a 2.0L container, and 1.5 moles of phenylamine were added to thereaction, what will the new concentrations of the three ionic species be when…

Hydroxychloroquine (HQ) was used to treat coronavirus. The proposed mechanism for the action of HQ is to enter into the cytoplasm of the cell and increase intracellular pH from 4.7 to 6.3 and to stop the virus from entering the cell. Looking at the structure of HQ, and the fact that the intracellular pH is increased when HQ is present, how does HQ increase the pH? Hydroxychloroquine is a weak Bronsted base. Hydroxychloroquine is a weak Arrhenius base Hydroxychloroquine is a weak Lewis acid Hydroxychloroquine is a weak Bronsted acid.

Rain with a pH below 5.6 is considered acid rain. The principal cause of acid rain is coal-burning electrical power plants (sulfurous and sulfuric acids are formed in the atmosphere from this). Any combustion reaction that produces high temperature can also produce acid rain (nitrous and nitric acid are produced in the atmosphere from this). Thus, automotive engines are also an important contributor to acid rain. Acid rain harms both living and nonliving things in a variety of ways. What solution/s can you propose to combat acid rain?
