Oh how we lament the poor spelling.

If you google muriatic, you will get 22,900 hits, 
google muratic (without the 'i' ) and you get 2,460 hits and it also 
offers the correct spelling.

I often will change the subject line when the topic shifts, 
especially when the thread gets a little long.

That would be a hint to all you who might ever search the archives.  
This list is much better than most for NOT posting  'newest newbie 
question' that then has 30 replies.

A word on chemical storage...

Whatever bottle you use, it would be wise to get a container, like a 
tupperware bucket that is of greater volume than your container and 
place your container in that bucket.  

That does a few things.
One, it adds a level of protection from bumping.
Another it adds a space around the container for atmospheric 
reactions and a place to catch those.
It also adds a layer of containment if two chemicals were to break 
and it prevent them from mixing.

Also, make sure the secondary containment vessel is compatible with 
the chemical which it will hold.

Also, one can place some substance in the bottom of the containment 
vessel that will neutralize the acid or base in the event of a leak.


Anybody wanna offer what is compatible with the chemicals in this 
thread ?  That would put more data into a single place to find it for 
a future search.


Muriatic acid, aka HCL, aka hydrochloric acid ?


H2O2, aka, Hydrogen peroxide?


Cupric chloride ?
