Chapter 19 Solubility product principle COURSE OUTCOMES ADDRESSED IN THIS CHAPTER: I. Thinking and decision-making A. Gather and comprehend information from reading texts, handouts, lecture manual and lecture notes, and making observations: 1. memorize key information and put it into an appropriate context 2. translate information from one form to another(written words to symbols, diagrams, physical actions, etc.) B. Analyze information: 1. solve a problem/come to a conclusion by working inductively or deductively 2. make accurate observations 3. make reasonable inferences from observations 4. select appropriate formulae to solve a problem 5. recognize assumptions 6. identify errors in reasoning C. Apply general principles to specific situations II. Mathematical reasoning A. Apply basic mathematical operations to solve numerical problems 1. add, subtract, multiply and divide exponential numbers 3. apply the use of significant figures where appropriate in calculations B. Use basic algebraic manipulations to re-arrange relationships III. Scientific competence: A. Apply the reasoning process used in science: 1. define and classify information unique to chemical systems 2. recognize patterns within chemical systems and be able to compare these B. Conduct experiments: 1. make and record accurate observations 2. generate hypotheses from observations 3. categorize and graphically represent data 4. formulate conclusions PERFORMANCE CRITERIA FOR ABILITY OUTCOMES: 1. Define or explain: saturated solution hydrolysis solubility complex ion solubility product constant, K sp weak electrolyte fractional precipitation common ion effect nucleation

2. Be able to write the equation for the dissolution equilibrium for any slightly soluble salt. 3. Be able to formulate the K sp (solubility product constant) expression for any slightly soluble salt. 4. Given the solubilities of its component ions, be able to determine a value for the K sp of any slightly soluble salt. 5. Given the value of its K sp , be able to calculate the solubility of any slightly soluble salt. 6. Given the value for K sp and the initial concentrations of the ions involved, be able to determine if a precipitate will form. 7. Given the values for the K sp 's of two insoluble salts and the initial concentrations of their component ions, predict which compound precipitates first. 8.
