I wasn't able to find any demo video's on YouTube for muriatic acid. There's one showing Sulphuric Acid having water added with virtually no effect but the acid looked impure to start off (dark brown color) so I can't be sure it's a good representation. I checked out a chemistry forum online and thought this post summed it up fairly well:
"......I also noticed in your post that you talked about adding water to an acid. PLEASE don't do that. ALWAYS add a concentrated acid to water and not the reverse. Many people underestimate the amount of heat generated when a concentrated acid is diluted, and if you're not careful you may wind up with a face full of concentrated acid. (As the water instantly boils and sprays the acid up in a steam explosion). Even if you're confident in what you're doing, it's always best to make it a habit to add the concentrated to the dilute."
I believe muriatic is less powerful than the sulfuric acid the poster was talking about, but it doesn't hurt to follow the same general guidelines.
Thanks for being positive and receptive to the caution.
