Chlore et Calcium – \u00c0 propos des \u00e9l\u00e9ments<\/h2>\n<\/div><\/div>\n

\n

Chlore<\/h3>\n

Le chlore est un gaz jaune-vert \u00e0 temp\u00e9rature ambiante. C’est un \u00e9l\u00e9ment extr\u00eamement r\u00e9actif et un agent oxydant puissant: parmi les \u00e9l\u00e9ments, il a la plus haute affinit\u00e9 \u00e9lectronique et la troisi\u00e8me \u00e9lectron\u00e9gativit\u00e9 la plus \u00e9lev\u00e9e, derri\u00e8re seulement l’oxyg\u00e8ne et le fluor.

Calcium<\/h3>\n

Le calcium est un m\u00e9tal alcalino-terreux, c’est un m\u00e9tal jaune p\u00e2le r\u00e9actif qui forme une couche d’oxyde-nitrure sombre lorsqu’il est expos\u00e9 \u00e0 l’air.\u00a0Ses propri\u00e9t\u00e9s physiques et chimiques sont les plus similaires \u00e0 celles de ses homologues plus lourds, le strontium et le baryum.\u00a0C’est le cinqui\u00e8me \u00e9l\u00e9ment le plus abondant de la cro\u00fbte terrestre et le troisi\u00e8me m\u00e9tal le plus abondant, apr\u00e8s le fer et l’aluminium.<\/p>\n<\/div>

Chlore et Calcium – Applications<\/h2>\n<\/div><\/div>\n
\n
\n
\n

Chlore<\/a><\/h3>\n

Le chlore est utilis\u00e9 dans la fabrication d’une large gamme de produits de consommation, dont environ les deux tiers sont des produits chimiques organiques tels que le chlorure de polyvinyle (PVC), de nombreux interm\u00e9diaires pour la production de plastiques et d’autres produits finis qui ne contiennent pas l’\u00e9l\u00e9ment.\u00a0En tant que d\u00e9sinfectant courant, le chlore \u00e9l\u00e9mentaire et les compos\u00e9s g\u00e9n\u00e9rateurs de chlore sont utilis\u00e9s plus directement dans les piscines pour les maintenir hygi\u00e9niques.\u00a0Bien qu’elle soit peut-\u00eatre mieux connue pour son r\u00f4le dans la fourniture d’eau potable, la chimie du chlore contribue \u00e9galement \u00e0 fournir des mat\u00e9riaux de construction \u00e9conomes en \u00e9nergie, des composants \u00e9lectroniques, des fibres optiques, des cellules \u00e0 \u00e9nergie solaire, 93 % des produits pharmaceutiques vitaux, 86 % des compos\u00e9s phytosanitaires, des plastiques m\u00e9dicaux. , et beaucoup plus.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

\n

Calcium<\/a><\/h3>\n

La plus grande utilisation de calcium m\u00e9tallique est dans la sid\u00e9rurgie, en raison de sa forte affinit\u00e9 chimique pour l’oxyg\u00e8ne et le soufre.\u00a0Ses oxydes et sulfures, une fois form\u00e9s, donnent des inclusions d’aluminate de chaux liquide et de sulfure dans l’acier qui flottent.\u00a0Les compos\u00e9s de calcium sont utilis\u00e9s dans la fabrication d’insecticides, de peintures, de craie \u00e0 tableau noir, de textiles et de feux d’artifice.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
