CHEM 122 1st Edition Lecture 27 Outline of Last LectureI. Acid/Base ionization Constant a. Strength of acids and bases b. Calculations of weak acid and base solutionsOutline of Current Lecture II. Percent IonizationIII. Calculations of Weak Acid and Base SolutionsIV. Polytropic acidsCurrent LecturePercent Ionization: % ionization= Ionized concentration/ initial concentration x 100Calculations of Weak Acid and Base Solutions:- First write out the acid ionization equilibrium equation- Second write out the equilibrium law- Third find the concentrations using ICE table- Used x to find the concentrations, then use those to find the pH and the % ionization - As the concentration of the acid is reduce the equilibrium shifts to the right. Thisis a general feature of all equilibriums.- As the % ionization increases the concentrations decrease.- The process is the same for bases except you are calculating the OH- concentration directly.Polyprotic Acids: acids with more than once acidic hydrogen atom- Monoprotic acid: acids with only one acidic hydrogen.- Polyprotic acids ionize in successive steps, losing an H+ each step.These notes represent a detailed interpretation of the professor’s lecture.
