So Ive been helping my professor clean out the rock room at CSU. Well the other day he comes to me with a brown glass gallon jug and a 25 pound tub of Baking Soda. Apparently the bottle was HCl, Hydrochloric Acid but he didnt know the concentration so it had to be 'neutralized'. This amounts to making a big volcano like you did in grade school that oozes acid Needless to say I quickly put on an apron, rubber gloves, and goggles. Remember Always Add Acid. I took a ten gallon bucket and put some water in it and a few scoops of baking soda. Then added acid until the fizz reached half up the bucket. It was very cool watching the reaction. So I repeated this process: baking soda, acid, baking soda, acid... Well eventually I put what was left of the acid in the bucket and poof it overflowed all over the floor. OOPS! All in all it took 45 minutes, 10 pbs. of baking soda, a gallon of acid, and a roll of paper towels to equalize the reaction. The Result: One ten gallon bucket of salt water, remember the reaction of an acid and a base is a salt.
