Assume all quiz questions are for 25∘C. What is the hydroxide ion concentration for a solution with [H3O+]=0.0035M ? (Hint: use Kw ) 2.9×10−12M 0.0070M 3.5×10−17M 0.0035M
What is the pH of a solution with [H3O+]=0.0035M ? (same solution as #1) 16.5 2.46 2.15 11.5
What can you say about of a solution with [H3O+]=0.0035M ? (same solution as #1, 2) It is neutral. It is basic. We cannot determine if it is acidic or basic. It is acidic.
What is the pH of a 0.015M hydroiodic acid, HI ? (Hint: What is the [H3O+]?) 1.50 1.82 1.52 1.04
What is the pH of a 0.015M hypochlorous acid, HClO, which has a Ka=2.9×10−8 ? (Hints: What is the [H3O+]? Write out the acid ionization reaction with an ICE table, expression for Ka, and solve for x using the " x is small" approximation/assumption.) 1.82 3.34 2.42 4.68
What is the percent ionization of a 0.015M hypochlorous acid, HClO, which has a Ka =2.9×10−8 ? (Hints: Same solution as the previous problem, #5. What is the [H3O+]?) 4.86% 0.14% 1.39% 1.82%
