The neutralization of an acid with a base yields a salt (and usually water) in aqueous solution. (a) Calculate the pH when 59.0 mL of 0.237 M perchloric acid is mixed with 59.0 mL of 0.237 M sodium hydroxide solution at 25 °C Number pH-

. Using Fig. 16.3, list the approximate pH value of live “everyday” solutions. How do the familiar properties (such as the sour taste for acids) of these solutions correspond to their indicated pH?

In a particular solution, acetic acid is 11% ionized at 25 C. Calculate the pH of the solution and the mass of acetic acid dissolved to yield 1.00L of solution.

What is the pH of a solution obtained by mixing 235 mL of NaOH with a pH of 11.57 and 316 mL of Sr(OH)2 with a pH of 12.09? Assume that volumes are additive.

Consider a 0.45 M solution of ascorbic acid,H2C6H6O6, one form of Vitamin C. H2C6H6O6(aq)HC6H6O6(aq)+ H+(aq)K a=7.9 10 5 HC6H6O6(aq)C6H6O62(aq)+ H+(aq)K a=1.6 10 12 Calculate the pH of this solution and estimate [ HC6H6O6 ] and[ C6H6O62 ].

Phthalic acid ( H2C8H4O4, abbreviated H2Ph ) is a diproticacid. Its ionization in water at 25°C takes place in twosteps: H2Ph(aq)+H2O(l)H3O+(aq)+HPh(aq)Ka1=1.26103H2Ph-(aq)+H2O(l)H3O+(aq)+Ph2(aq)Ka2=3.10106 If 0.0100 mol of phthalic acid is dissolved per liter ofwater, calculate the equilibriumconcentrations of H2Ph,HPh,Ph2, and H3O+.

You are asked to determine whether an unknown white solid is acidic or basic. You also need to say whether the acid or base is weak or strong. You are given the molar mass of the solid and told that it is soluble in water. Describe an experiment that you can perform to obtain the desired characteristics of the white solid.
