The toxicological properties of this material have not been fully investigated. Potential Health Effects Eye: May cause eye irritation. Skin: May cause skin irritation. Ingestion: May cause gastrointestinal irritation with nausea, vomiting and diarrhea. Inhalation: May cause respiratory tract irritation. Chronic: No information found. Section 4 - FIRST AID MEASURES Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. Skin: Get medical aid if irritation develops or persists. Flush skin with plenty of soap and water. Ingestion: If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid if irritation or symptoms occur. Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid if cough or other symptoms appear. Notes to Physician: Section 5 - FIRE FIGHTING MEASURES General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing Media: Use extinguishing media most appropriate for the surrounding fire.

2.称取30g碳酸氢钾，溶解于300mL水中，保持温度在3℃左右，慢慢通入二氧化碳，使之饱和。用磁力搅拌器充分搅拌，缓慢滴加已经冷却到3℃的0.1mol/L的ZnSO4水溶液700mL，然后放在冰箱中，保持在10℃以下，静置3～4天后，再在20℃室温下放置2～3天。这样便会有微细的结晶性物质沉降下来。用水倾泻洗涤此结晶性沉淀，并使得溶液上部的漂浮性物质流出。将洗涤后的沉淀转移至滤纸上，用水洗涤至不含硫酸根离子。于130℃下干燥。
