    C: Na2SO3 yan\u0131c\u0131 de\u011fildir ancak baz\u0131 oksitleyici maddelerle reaksiyona girerek solunumu tahri\u015f eden ve yan\u0131c\u0131 olabilen k\u00fck\u00fcrt dioksit a\u00e7\u0131\u011fa \u00e7\u0131karabilir.<\/p>\n

    S: Sodyum s\u00fclfit yerel olarak nereden sat\u0131n al\u0131n\u0131r?<\/h3>\n

    C: Na2SO3 kimyasal tedarik \u015firketlerinden, end\u00fcstriyel tedarik\u00e7ilerden ve baz\u0131 \u00f6zel perakendecilerden sat\u0131n al\u0131nabilir. Ayr\u0131ca baz\u0131 yerel donan\u0131m ma\u011fazalar\u0131nda veya ev geli\u015ftirme merkezlerinde de mevcut olabilir.<\/p>\n

    Soru: Hangi g\u0131dalar sodyum s\u00fclfit i\u00e7erir?<\/h3>\n

    C: Na2SO3 genellikle \u015farap, bira, kurutulmu\u015f meyveler ve baz\u0131 i\u015flenmi\u015f etler gibi g\u0131dalarda koruyucu olarak kullan\u0131l\u0131r.<\/p>\n

    S: Hangi \u00fcr\u00fcn sodyum s\u00fclfite e\u015fittir?<\/h3>\n

    C: Sodyum bis\u00fclfit, baz\u0131 uygulamalarda Na2SO3’\u00fcn yerine kullan\u0131labilen benzer bir bile\u015fiktir. Di\u011fer ikameler aras\u0131nda sodyum metabis\u00fclfit veya potasyum metabis\u00fclfit yer alabilir.<\/p>\n","protected":false},"excerpt":{"rendered":"
