La sosa cáustica o hidróxido de sodio es un sólido blanco, delicuescente, muy soluble en el agua, que funde a 320 °C. Es una base fuerte, análoga a la potasa, aunque menos cáustica que ella, y obra sobre los ácidos para dar sales de sodio, y sobre los ésteres, para saponificarlos.  5, record 1, Spanish, - hidr%C3%B3xido%20de%20sodio

[Dans la cellule électrolytique à cathode de mercure], le mercure joue un rôle de cathode : étant donné que la surtension du gaz hydrogène est beaucoup plus élevée avec une électrode de mercure, il y a réduction de Na⁺ et non de H₂O. Le sodium ainsi produit est dissous dans le mercure, ce qui forme un amalgame qu'une pompe achemine vers un décomposeur, où le sodium dissous réagit avec l'eau pour produire de l'hydrogène [...] On peut, à partir de la solution aqueuse, récupérer du NaOH [hydroxyde de sodium] solide relativement pur; le mercure régénéré, quant à lui, retourne à la cellule électrolytique.  1, record 2, French, - d%C3%A9composeur

En el proceso de celda de mercurio, éste actúa como cátodo en el cual se produce una amalgama con sodio y en el ánodo se depositan iones de cloro. Además, se desprende cloro en estado gaseoso. Posteriormente, en un reactor separado llamado descompositor [...], la amalgama de sodio reacciona con agua y se produce hidrógeno en estado gaseoso y solución de sosa cáustica al 50% con poco contenido de cloruro de sodio.  1, record 2, Spanish, - descompositor
