Unformatted text preview: ekk86 – hw05 – Holcombe – (53570) 1 This print-out should have 25 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points Which of the following is true for strong acids? 1. They are weak electrolytes. 4. They react only with weak bases. 3. Aqueous solutions of strong acids have a high pH. 4. They react only with strong bases. 5. After they lose a proton, they give rise to strong conjugate bases. 6. They are almost totally ionized or disso- ciated in aqueous solutions. 002 10.0 points If a bottle of wine is not sealed properly, oxygen can seep in and oxidize some of the alcohol to produce acetic acid. What would this do to the pH in the bottle? 1. It would decrease the concentration of hydrogen ions in solution. 2. It would not affect the pH since the bottle had not been opened. 3. It would increase the pH relative to a bottle where no oxidation had taken place. 4. The pH would stay near neutrality be- cause there is water in the wine. 5. It would decrease the pH relative to a bottle where no oxidation had taken place. 003 10.0 points As NaOH is added to an aqueous solution, the pH will 1. increase. 2. increase or decrease depending on whether the initial pH is higher or lower than 7. 3. Not enough information is given to solve the problem....
