This hydrolysis occurs because of the extreme basicity of the Se 2− ion. Na 2 Se + H 2 O → NaHSe + NaOH. Similarly, sodium selenide is readily oxidized to polyselenides, a conversion signaled by off-white samples. Sodium selenide reacts with acids to produce toxic hydrogen selenide gas. Na 2 Se + 2 HCl → H 2 Se + 2 NaCl.
Sodium selenite usually is prepared by the reaction of selenium dioxide with sodium hydroxide: [1] SeO 2 + 2 NaOH → Na 2 SeO 3 + H 2 O. The hydrate converts to the anhydrous salt upon heating to 40 °C. According to X-ray crystallography, both anhydrous Na 2 SeO 3 and its pentahydrate feature pyramidal SeO 32−.
