Disposal container for muriatic acid

chemicalsdisposalsafety

I need to do work with muriatic acid and was wondering if storing the waste (12 Oz of acid per gallon of water) is okay to do in a regular plastic 5 gal bucket. My concern is whether the acid could melt the plastic then spill out. Should I get a metal bucket just in case?

A metal bucket is much MORE prone to be attacked by acids in general than most plastics, especially those commonly used for buckets.

As it's "waste acid" throw in a box or two of baking soda and you'll neutralize it right then and there. Preferably outside due to the release of carbon dioxide. Or use marble/limestone chips or dust.
