- Consider the following four biological solutions: (1) bile, pH 8.0, (2) blood, pH 7.4, (3) urine, pH 6.0, and (4) gastric juice, pH 1.6. a. Which solution has the lowest [H3O+]? b. Which solution has the lowest [OH]? c. List the solutions in order of decreasing acidity. d. List the solutions in order of increasing basicity.arrow_forwardUsing the diagrams shown in Problem 10-37, which of the four acids is the weakest acid?arrow_forwardYou are asked to calculate the H+ concentration in a solution of NaOH(aq). Because sodium hydroxide is a base, can we say there is no H+. since having H+ would imply that the solution is acidic?arrow_forward
- Write equations that show NH3 as both a conjugate acid and a conjugate base.arrow_forwardWhich of the following substances are acids in terms of the Arrhenius concept? Which are bases? Show the acid or base character by using chemical equations. a P4O10 b Na2O c N2H4 d H2Tearrow_forwardWill the following oxides give acidic, basic, or neutral solutions when dissolved in water? Write reactions to justify your answers. a. CaO b. SO2 c. Cl2Oarrow_forward
- Pure liquid ammonia ionizes in a manner similar to that of water. (a) Write the equilibrium for the autoionization of liquid ammonia. (b) Identify the conjugate acid form and the base form of the solvent. (c) Is NaNH2 an acid or a base in this solvent? (d) Is ammonium bromide an acid or a base in this solvent?arrow_forwardAn antacid purchased at a local drug store has a pOH of 2.3. Calculate the pH, [H], and [OH] of this solution. Is the antacid acidic or basic?arrow_forward
