DR. JIM BLOXTON’S OPTIONAL STUDY GUIDE TO ACCOMPANY CHEM 1021 CHAPTER 8 ACIDS AND BASES Note: This is an optional study guide. This study guide is not an exhaustive list of questions that could appear on quizzes or exams. These are sample questions that may or may not be used on a quiz or midterm exam or final exam. Other questions that are not found on this study guide will be on actual quizzes, midterm and final exams. It is important to do all of the homework problems that are in your Chem 1021 lecture text in addition to the questions in this study guide. Make sure that you do all of the Chemical Connections homework questions that have assigned. Learn the basic principles and then be prepared to apply the principles to problems that you have not seen before. Note: It is very important to remember that Chemistry is a cumulative topic and that the material that was covered in previous chapters needs to be reviewed as this material will continue to reappear in concepts that are needed to solve new problems. The following questions are to be answered from CHEM 1021 CHAPTER 8 LECTURE TEXT, LECTURE NOTES AND LECTURE SLIDES. 1. What are some common acids and bases that we encounter on a regular basis outside of the chemistry laboratory? 2. According to the Arrhenius definition what is an acid? Give both the original and modified definitions. 3. According to the Arrhenius definition what is a base? Give both the original and modified definitions. 4. Give the definition, formula and chemical equation for the formation of a hydronium ion. 5. What is the relationship between H + , proton and H 3 O + in acid base chemistry? 6. What happens when hydrogen chloride gas is dissolved in water? Show a chemical equation and give the names of all reactants and products. Include the states. Indicate the major and minor species. How do these products relate to the classification of hydrogen chloride as an acid? 7. Use curved arrow formalism to show what happens when hydrogen chloride gas is dissolved in water. Explain what the flow of arrows mean and what bonds are forming and breaking. 1

8. What happens when a metal hydroxide base such as sodium hydroxide is dissolved in water? Show a chemical equation and give the names of all reactants and products. Include the states. How do these products relate to the classification of sodium hydroxide as a base? 9. What happens when a weak base such as ammonia is dissolved in water? Show a chemical equation and give the names of all reactants and products. Include the states. What are the major and minor species in this equation? How do these products relate to the classification of ammonia as a base? 10. Use curved arrow formalism to show what happens when a weak base such as ammonia is dissolved in water. Explain what the flow of arrows mean and what bonds are forming and breaking.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
