- Tile pH of a solution of household ammonia, a 0.950 M solution of NH3 is 11.612. Determine Kb for NH3 from these data.arrow_forwardChloroacetic acid, HC2H2ClO2, has a greater acid strength than acetic acid, because the electronegative chlorine atom pulls electrons away from the OH bond and thus weakens it. Calculate the hydronium-ion concentration and the pH of a 0.0020 M solution of chloroacetic acid, Ka is 1.3 103.arrow_forwardCalculate the pH and the pOH of each of the following solutions at 25 C for which the substances ionize completely: (a) 0.000259 M HClO4. (b) 0.21 M NaOH. (c) 0.000071 M Ba(OH)2. (d) 2.5 M KOHarrow_forward
- Calculate the pH and the pOH of each of the following solutions at 25 C for which the substances ionize completely: (a) 0.200 M HCl. (b) 0.0143 M NaOH. (c) 3.0 M HNO3. (d) 0.0031 M Ca(OH)2arrow_forwardAt 25 C, a 0.10% aqueous solution of adipic acid, C5H9O2COOH, has a pH of 3.2. A saturated solution of the acid, which contains 1.44 g acid per 100. mL of solution, has a pH = 2.7. Calculate the percent dissociation of adipic acid in each solution.arrow_forwardWrite the formula and name for the conjugate acid of the following substances. (The information in Tables 15.6 and 15.8 may be helpful.) (a) N2H4 (b) NO2 (c) ClO4 (d) Iarrow_forward
- Are solutions of the following salts acidic, basic, or neutral? For those that are not neutral, write balanced chemical equations for the reactions causing the solution to be acidic or basic. The relevant Ka and Kb values are found in Tables 13-2 and 13-3. a. NaNO3 b. NaNO2 c. C5H5NHClO4 d. NH4NO2 e. KOCl f. NH4OClarrow_forwardEach of the following statements concerns a 0.010 M solution of a weak acid, HA. Briefly describe why each statement is either true or false. a [HA] is approximately equal to 0.010 M. b [HA] is much greater than [A]. c [OH] is approximately equal to [H3O+]. d The pH is 2. e The H3O concentration is 0.010 M. f [H3O+] is approximately equal to [A].arrow_forwardIn the following net ionic reaction, identify each species as either a Brnsted-Lowry acid or a Brnsted -Lowry base: CH3COO(aq)+HS(aq)CH3COOH(aq)+S2(aq). Identify the conjugate of each reactant and state whether it is a conjugate acid or a conjugate base.arrow_forward
- Note whether hydrolysis occurs for each of the following ions. If hydrolysis doe occur, write the chemical equation for it. Then write the equilibrium expression for the acid or base ionization (whichever occurs). a CH3NH3+ b Cl c ClO2 d CO32+arrow_forwardIndicate 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_forward
