You didn't specify dill, sweet, bread & butter, etc., but I'll answer for dill pickles, the most popular type of pickle, and probably the one you meant.
Besides cucumbers (the main ingredient) all dill pickles have water, vinegar and salt as primary brine ingredients, as well as some form and combination of dill as a spice. - sprigs of dill (leaves), dill seed (different than the leaves or sprigs, more like a spice than an herb), dill flowers (the head of dill where the seeds eventually come from).

Pickling lime used to be an accepted method of adding crispness to pickled cucumbers. The USDA no longer recommends use of pickling lime. Pickling lime is alkaline and must all be washed off of the cucumbers or it can result in a less acidic pickling solution. It the pickling solution is not acidic enough it can allow botulism an environment in which to grow. Botulism cases have been linked to this situation and this is the reason it is no longer recommended.

There are many ways to 'pickle' cucumbers and vegatables. The most common recipes for pickling involve vinegar (distilled or apple cider vinegar) and salt. Both distilled and apple cider vinegar contain acetic acid. So your answer is 'acid.'
Pickling salt is the same as table salt but without iodine and caking agents added. Salt that is labeled "kosher salt" may be free of these additives and can be used in place of pickling salt but you'd have to check the package labeling to confirm the lack of additives.
