Fill a test tube with HCL solution before adding a piece of metal?

[Song]

Why it would be unwise to almost completely fill a test tube with HCL solution before adding a piece of metal? Is it because it's a acidic solution?

Thanks

Let's see some analysis from your part first...start with some equations, which should be located in your text explicitly.

Acid and metal can react fiarly vigourously. U wouldn't want acid bubbling over the edge and onto ur hands. Although in my experience its not near as bad as ud think.

Yes, I've heard of some cases of individuals coming to the lab intoxicated...and also those who have actually, purposefully, took a sip of the ethanol reagents during a session.

Except for what Blackwizard said about "Acid and metal can react fiarly vigourously", there is no other reason for which (either metal or acidic solution) goes into test tube first?
