Hi guys! Since i'm no chemist i have no idea what i actually inhaled so i'm asking for your help! I mixed solution of 30 grams sodium hydroxide,1 gram sodium nitrate and sodium nitrite in 1L water. This is used in cleaning metals like aluminum. So i had this solution in a glass,it has been dried up on the walls. I dropped few drops of 10% h2so4, 0.1% glycolic and 0.1% glycerine. It started bubbling so i thought oh its being neutralized by the hydroxide and i had a close snif. Wow what a sharp smell it was! I immediately washed it of in the sink. Anybody has idea what i inhaled? I hope not nox?? Any answer is appreciated! Regards from Europe!
