Dave, Daddy Dear, do you remember all those years ago when you adopted me? Waiting for my "Little Rifle"... I wish!
Folks, if you are going to mix acid and water, PLEASE remember to Always Add Acid! IOW, if you are diluting the acid, say 3:1 (water:acid), put your water in first, THEN add the acid. Same thing with a strong base - add the base to the water.
If you add the water second, you will get a severe exothermic reaction, possibly spattering the acid into your eyes, on your arms, etc.
