Testing rocks

[enchanted]

Anybody know how to test rocks for ph adjusters, etc....

I'm going down to the river (about 1/2 a mile from me. ) to find some nice rocks, but I don't want them to affect the ph.

Scratch the rock and drip vinegar on it. If a reaction occurs, high pH. Not sure if this is always relaible, though.

see this pinned topic I wrote rocks

do you have a nitrAte test? if so, you can use bottle #1 instead of vinegar to carry out Temptestuousfury's method. (it's hydrochloric acid....)

failing that, get a bowl of water, test the pH, leave the rocks in it overnight, test the pH again, see if it's changed.

oh, and clean all rocks you find very thoroughly, and make sure they dont look to have metal in them.

I collected my rocks (some flat just so I could make caves. ).

Now I just have to figure out where test solution 1 for nitrate walked off to, since I don't have any vinegar.

I know boiling is a good option for cleaing, how long should they boil for?

Thanks,

a minimum of 20 mins

Alright, I have 3 rocks to boil for 20 minutes. I haven't tested the rest yet.
