CAS 7440-23-5
:Sodium
Description :
Sodium, avec le numéro CAS 7440-23-5, est un métal alcalin hautement réactif appartenant au groupe 1 du tableau périodique. Il se caractérise par son apparence douce et blanc argenté et est connu pour sa faible densité, étant moins dense que l'eau. Sodium a un point de fusion d'environ 98 degrés Celsius et un point d'ébullition d'environ 883 degrés Celsius. Il perd facilement un électron pour former un cation (Na+), ce qui le rend hautement réactif, en particulier avec l'eau, produisant de l'hydroxyde de Sodium et du gaz hydrogène. Cette réactivité nécessite que Sodium soit stocké sous huile ou dans une atmosphère inerte pour éviter qu'il ne réagisse avec l'humidité de l'air. Sodium joue un rôle crucial dans les systèmes biologiques, en particulier dans la fonction nerveuse et l'équilibre des fluides. Il est également un composant essentiel dans diverses applications industrielles, y compris la production de verre, de savons et en tant qu'échangeur de chaleur dans les réacteurs nucléaires. En raison de sa réactivité, Sodium doit être manipulé avec précaution et des mesures de sécurité appropriées doivent être prises lors de la manipulation de cet élément.
