I'm going to use HCL (Hydrochloric acid) to test if my gravel is safe. Should I test the gravel with full strength HCL or should I dilute it? Thanks.

p.s. I have a science teacher helping me with this so I don't hurt myself...

Most gravel purchased at the store is inert any way but any rocks you gather from streams or rivers should be tested.
It's much safer to test with vinegar. If it bubbles it's only safe to use in tanks needing a high pH.
What ever you test with make sure you rinse what you test very thoroughly.

it's mined from the Rocky Mountains by a friend who pans for gold. I've read that vinegar isn't strong enough of an acid to test rocks but I did the vinegar test and it didn't bubble. I just wanted to make sure it's ok.

I used a slightly diluted 12M HCL solution and no bubbles. I will be getting a 1M HCL solution for future testing so I don't need to test rocks in a science lab. Thanks everyone.
