Which solution has the highest [H3O+]? b. Which solution has the highest [OH]? c. List the solutions in order of increasing acidity. d. List the solutions in order of decreasing basicity.arrow_forwardWrite equations that show H2PO4- acting both as an acid and as a base.arrow_forwardPure 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_forward
- Which 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_forwardConsider 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_forwardDetermine whether aqueous solutions of the following salts are acidic, basic, or neutral: (a) Al(NO3)3. (b) RbI. (c) KHCO2. (d) CH3NH3Brarrow_forward
- Indicate whether each of the following samples is acidic, basic, or neutral. a. butter, pH 6.1 b. lemon juice, pH 2.2 c. peach, pH 3.5 d. milk of magnesia, pH 10.5arrow_forwardFor each of the following pairs of acids, indicate whether the first member of the pair is a stronger or weaker acid than the second member of the pair. a. HNO3 and HNO2 b. HF and HBr c. H2CO3 and HClO3 d. HCN and HClarrow_forwardYou are asked for the H+ concentration in a solution of NaOH(aq). Because sodium hydroxide is a strong base, can we say there is no H+. since having H+ would imply that the solution is acidic?arrow_forward
- Ethanol (ethyl alcohol), CH3CH2OH, can act as a BrnstedLowry acid. Write the chemical equation for the reaction of ethanol as an acid with hydroxide ion, OH. Ethanol can also react as a BrnstedLowry base. Write the chemical equation for the reaction of ethanol as a base with hydronium ion, H3O+. Explain how you arrived at these chemical equations. Both of these reactions can also be considered Lewis acid base reactions. Explain this.arrow_forwardIn each of the following acid-base reactions, identify the Brnsted acid and base on the left and their conjugate partners on the right. (a) HCO2H(aq) + H2O() HCO2(aq) + H3O+(aq) (b) NH3(aq) + H2S(aq) NH4+(aq) + HS(aq) (c) HSO4(aq) + OH(aq) SO42(aq) + H2O+()arrow_forwardHome gardeners spread aluminum sulfate powder around plants to increase the acidity of the soil. Describe the chemistry at the nanoscale level for such a soil treatment.arrow_forward
