Anything you're going to powder coat can just be sanded. In fact, as long as the old chrome isn't peeling, I don't see why you even need to remove it. If it is peeling, just sand it down to a uniform smoothness and the powder coat will cover it. Remember, unlike plating, powdercoating does not rely on the finish of the item for polish or gloss.
Muriatic acid is Hydrochloric Acid (HCI), you can get it at pool supply stores or large hardware stores and costs less than $5 bucks a gallon. It's commonly used to lower the Ph in swimming pools or as a concrete driveway cleaner. As long as you respect it and follow safety guidelines, using it shouldn't be a problem. Wear goggles and gloves, use in ventalated area, don't breath fumes, NEVER mix with other cleaning chemicals and if diluting with water, it's ALWAYS acid into the water, NEVER water into the acid (dumping water into acid intantly creates a heat reaction in the water that can cause it to boil or vaporise, splashing hot acid everywhere).
Sandblasting/bead blasting the chrome off would be the way I would do it, if I had access to such a system. It's fast and direct with minimal clean up.

One more thing I am also considering sand balsting the chrome off, would this be good?
