I needed to remove ceramic tile from bathroom wall to make repairs, now I need to clean the mortar from the back of the tiles so they can be reset on the wall. Looking for what will work best.

Electric sander and heavy grit sand paper. If you don't have one, you may be able to rent from your local Home Depot. Good luck.
Scraping and a wire brush in a drill. Wear hand and eye protection. You can use a grinder.
Apply muriatic acid directly to the back of a piece of tile if the mortar is particularly thick, such as more than 1/8 inch. Use a paint brush and coat the mortar with pure acid. As it loosens the concrete, use your scrub brush with water to gently scrub andremove the excess. Apply more as needed.
