Yes - for part A you need an ICE table. Part B - pH should be neutral (since Cl- as a conjugate base is not active - and NaCl is the salt of a Strong Acid/Strong Base neutralization - pH = 7.0)

Explanation:

For Part A, you need the Kb of Acetate ion. Or you can use the Acetic Acid Ka to get the Kb. #K_B = K_w/K_A#

From there, just ICE table away and solve for [OH-], then get pOH and then pH.
