-Be able to classify acids as strong or weak (>1 = strong; <1 = weak) (honors only)

Example 4. The Ka of an unknown acid is 2 x 10-5 M. This is a ______________ acid.

-Be able to identify the strongest and weakest acid from a list of Ka values (honors only) -Be able to label acidic and basic solutions as dilute/concentrated, strong/weak, acid/base. (honors only)

Example 5. A 3.2 M solution of hydrochloric acid is an example of a ________ ___________ acid.

c. [H+] and [OH-] calculations worksheet -Be able to use Kw to determine [H+] or [OH-]. (honors only; whole numbers for rest) (remember, some of these will require the use of a calculator)

Example 5. For an aqueous solution, if [H+] is 2.1 x 10-4 M, then [OH-] must be _______ M.

d. pH and pOH calculations (also known as the worksheet from Hell) -Be able to determine pH, pOH, [H+], and [OH-] when given one of those pieces of data
