SULFITES sodium hydrogen sulfite sodium hydrosulfite sodium sulfite	-	-	-	- -	All sulfites are toxic if ingested. Most metal sulfites irritate the stomach by production of sulfurous acid. When sulfites are heated to decomposition, toxic sulfur dioxide is produced. Disposal: Sulfite solutions (not containing heavy metals) may be discharged down the sink (to sewer) after treatment. 1. Solutions should be made acidic in a fume cupboard to expel sulfur dioxide gas. 2. At completion of the reaction the solution should be made basic (use sodium hydroxide) to pH: 8-10. Then discharged down the sink. ALSO SEE SEPARATE LISTING FOR EACH CHEMICAL. Also see Appendix E
