WebJan 23, 2024 · The Reaction between Sodium Metal and Ethanol. If a small piece of sodium is dropped into ethanol, it reacts steadily to give off bubbles of hydrogen gas and leaves a colorless solution of sodium ethoxide: C H 3 C H 2 O N a. The anion component is an alkoxide. (1) 2 C H 3 C H 2 O H ( l) + 2 N a ( s) → 2 C H 3 C H 2 O ( a q) − + 2 N a ( a q ... Sodium perborate releases oxygen rapidly at temperatures over 60 °C. To make it active at lower temperatures (40–60 °C), one must mix it with a suitable activator, typically tetraacetylethylenediamine (TAED).
