26. What is the hydrogen ion concentration in a wheat flour and water solution if [OH-] = 1.0 x 10-8 M? Is the wheat
flour and water acidic, basic or neutral?
pOH = 8, pH = 6, [H+] = 1 x 10-6 M, ACIDIC
27. What is the pH of peaches if the [OH-] = 3.16 x 10-11 M? Are peaches acidic, basic, or neutral?
pOH = 10.5, pH = 3.5, ACIDIC
28. What is the [H+] concentration in eggs if [OH-] = 6.0 x 10-7 M? Are eggs acidic, basic, or neutral?
pOH = 6.22, pH = 7.78, [H+] = 1.6 x 10-8 M, BASIC
29. An aqueous solution contains a 0.0361 M OH- concentration. Calculate the pOH, pH and [H+]. Determine if the
solution is acidic or basic.
pOH = 1.44, pH = 12.56, [H+] = 2.75 x 10-13 M, BASIC
30. Lake Ontario has water with an [H+] of approximately 1.1 x 10-6 M. Determine whether the water is slightly
acidic or slightly basic.
pH = 5.96. ACIDIC
