dissolved in an acidic or alkaline environment only.
10. Stability and Reactivity (sulphuric acid, 30 ~ 38.5 %)
• Corrosive, nonflammable liquid
• Thermal decomposition at 338° C.
• Destroys organic materials such as cardboard, wood, textiles.
• Reacts with metals, producing hydrogen
• Vigorous reactions on contact with sodium hydroxide and alkalis.
