O carbonato de s\u00f3dio (497-19-8), Na2CO3, \u00e9 o sal de s\u00f3dio do \u00e1cido carb\u00f3nico. O produto puro \u00e9 um p\u00f3 branco e inodoro com forte alcalinidade. \u00c9 altamente higrosc\u00f3pico. \u00c9 facilmente sol\u00favel em \u00e1gua, formando uma solu\u00e7\u00e3o aquosa moderadamente alcalina.
\nO carbonato de s\u00f3dio \u00e9 amplamente utilizado em v\u00e1rios dom\u00ednios em todo o mundo. Uma das aplica\u00e7\u00f5es mais importantes do carbonato de s\u00f3dio \u00e9 o fabrico de vidro. De acordo com as estat\u00edsticas, cerca de metade da produ\u00e7\u00e3o total de carbonato de s\u00f3dio \u00e9 utilizada no fabrico de vidro. No processo de produ\u00e7\u00e3o de vidro, o carbonato de s\u00f3dio actua como um fundente no processo de fus\u00e3o do di\u00f3xido de sil\u00edcio.<\/p>","protected":false},"featured_media":4318,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[22],"product_tag":[24],"class_list":{"0":"post-4263","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-daily-chemicals","7":"product_tag-daily-chemicals","9":"first","10":"instock","11":"shipping-taxable","12":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product\/4263","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/comments?post=4263"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/media\/4318"}],"wp:attachment":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/media?parent=4263"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product_brand?post=4263"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product_cat?post=4263"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product_tag?post=4263"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
