I purchased Test Kit Plus reagents to test a blue e pill. The ones I bought were the marquis, mandelin, and the mecke. These all have sulfuric acid in them with other toxic chemicals in them. The marquis has sulfuric acid and formaldehyde. The marquis has sulfuric acid and ammonium metavanadate. The mecke has sulfuric acid and selenous acid in it. I broke the blue e pill in three small separate parts and put them all spaced out on one white ceramic plate. Then I put three drops of each reagent on the blue e pill. It turns out the blue e pill was meth. When I finished testing it I only put baking soda on top of the ceramic plate with the three reagents on top to neutralize it because of the sulfuric acid. It started to make sounds like a fizzing I guess that was the chemical reaction of it neutralizing. I was standing right over the plate when it was neutralizing. And I wasn't wearing any respiratory mask. My question is how dangerous are the fumes that come from these reagents when you put baking soda on top of it to neutralize it. Because I had a bad headache after and I'm worried.
