• What would be the pH of an aqueous solution with a concentration of H+ of 8.76 X 10-4 M? (is it going to be acid or basic)
• -log8.76 X 10-4 = 3.05 pH= 3.05 acid
• Whatwould be the pOH of an aqueous solution with a concentration of OH- of 1.29 X 10-10M? (is it going to be acid or basic)
• -log 1.29 X 10-10 = 9.88 pOH= 9.88 acid
• What would be the pOH of anaqueous solution with a concentration of H+ of 1.38 X 10-4M? (is it going to be acid or basic)
• -log 1.38 X 10-4 = 3.86 pH= 3.86 pOH = 14 -3.86= 10.14 acid
• What would be the pH of an aqueoussolution with a concentration of OH- of 1.54 X 10-5M? (is it going to be acid or basic)
• -log 1.54 X 10-5 = 4.81 pOH = 4.81 pH = 14- 4.81 = 9.19 base
• What would be the pH of an aqueoussolution with a concentration of OH- of 1.38 X 10-4 M? (is it going to be acid or basic)
• -log 1.38 X 10-4 = 3.86 pOH = 3.86 pH = 14 - 3.86 = 10.14 base
• What would be the pOH of an aqueoussolution with a concentration of H+ of 5.62 X 10-10M? (is it going to be acid or basic)
• -log 5.62 X 10-10 = 9.25 pH = 9.25 pOH = 14 - 9.25 = 4.75 base
• What would be the pOH of an aqueoussolution with a concentration of OH- of 1.38 X 10-7M? (is it going to be acid or basic)
• -log 1.38 X 10-7 =6.86 pOH = 6.86 base
• What would be the pH of an aqueous solution with a concentration of H+of 1.58 X 10-11M?
• -log 1.58 X 10-11= 10.8 pH = 10.8 base

• What would be the pH of an aqueous solution of Butyric Acid 0.15 M? (Keq= 1.54 X 10-5)
• H= √1.54X10-5 X 0.15 = 1.51 X10-3
• -log 1.51 X 10-3 = 2.82 pH = 2.82
• What would be the pH of an aqueous solution of Phosphoric Acid 0.25 M? (Keq= 7.24 X 10-3, one proton only)
• H= √ 7.24 X 10-3 X 0.25 = 4.25 X10-2
• -log 4.25 X 10-2 = 1.37 pH = 1.37
• What would be the pH of an aqueous solution of Carbonic Acid 0.13 M? (Keq= 4.27 X 10-7)
• H = √ 4.27 X 10-7 X 0.13 = 2.36 X 10-4
• -log 2.36 X10-4...
