Okay I cant seem to figure out how to write the hydrolysis equation for .10 M ZnCl2...this is a salt, are you supposed to first figure out if its acidic or basic ? I think this is pH neutral ??? What would the estimated Ka or Kb be for this ? Also for .10 M KAl(SO4)2 I'm lost on this one...what would the Ka or Kb be for this ?
