During your future endeavors in chemistry you will inevitably do a bunch of acid-base problems. Of the strong bases above, calcium hydroxide, strontium hydroxide, and barium hydroxide often trick students into making small mistakes. Why do you think that is the case? a. There is only half a mole of hydroxide per mole of compound. b. They are actually acidic rather than basic. c. Nothing special about these, all acid-base is confusing! d. There are two moles of hydroxide for each mole of these compounds.
