Activities
Mission AB1 Properties of Acids and Bases
Mission AB1 pertains to the characteristic properties of acids and bases. The mission consists of 24 questions organized into 6 Question Groups.
Mission AB2 Strong Acids and Strong Bases
Mission AB2 pertains to strong acids and bases. Students must know what a strong acid (and base) is, be able to identify common examples of strong acids and strong bases, know what a dissociation equation is, and perform simple computations to determine the ion concentrations if given the concentration of a strong acid (or base) solution. The mission consists of 36 questions organized into 9 Question Groups.
Mission AB3 Bronsted-Lowry Model of Acids and Bases
Mission AB3 pertains to Bronsted-Lowry model of acids and bases. Students must have some fluency with the proton transfer behavior of acids and bases in aqueous solutions. The mission consists of 40 questions organized into 10 Question Groups.
Mission AB4 Conjugate Acid-Base Pairs
Mission AB4 pertains to the concept of conjugate acid-base pairs. Students must understand Bronsted-Lowry proton-transfer model as the process by which acids and bases react to form new substances. The mission consists of 36 questions organized into 9 Question Groups.
Mission AB5 The Self-Ionization of Water
Mission AB5 pertains to water's tendency to undergo self-ionization. Students must be familiar with the terms amphiprotic, hydronium ion, hydroxide ion, ion product constant, and the mathematical relationship between Kw and the ion concentrations. No calculations are involved. The mission consists of 32 questions organized into 8 Question Groups.
Mission AB6 pH and pOH
Mission AB6 pertains to the \(\pH\) and \(\pOH\) scale. Students must be able to identify a solution as being acidic or basic based upon its \(\pH\) or \(\pOH\) value. The mission consists of 36 questions organized into 9 Question Groups.
Mission AB7 The Math of pH and pOH
Mission AB7 involves simple calculations of the \(\pH\) and \(\pOH\) from given values of the hydronium ion or hydoxide ion concentrations. Most students will be able to answer questions using "head math". The mission consists of 28 questions organized into 7 Question Groups.
Mission AB8 Comparing Strong and Weak Acids
Mission AB8 focuses on how strong acids and weak acids compare to one another. Students must understand the concepts of complete and partial dissociation. The mission consists of 32 questions organized into 8 Question Groups.
Mission AB9 Dissociation Constants
Mission AB9 pertains to the meaning of an acid or base dissociation constant. Students must be able to recognize the relationship between a \(\descriptive{K}{K,equilibrium constant}\) value and equilibrium concentrations and relate the \(\descriptive{K}{K,equilibrium constant}\) value to the strength of the acid or base and the extent of its dissociation. The mission consists of 28 questions organized into 7 Question Groups.
Mission AB10 Neutralization Reactions for Strong Acids with Strong Bases
Mission AB10 pertains to neutralization reaction between strong acids and strong bases. Students must understand the molecular equations and their mole ratios and use them to answer straightforward computational questions. The mission consists of 28 questions organized into 7 Question Groups.
Mission AB11 Neutralization Reactions for Strong Acid with Weak Base
Mission AB11 pertains to neutralization reactions involving strong acids with weak bases or weak bases with strong acids. The mission consists of 28 questions organized into 7 Question Groups.
