Specification: 25 kg\/bag<\/strong><\/p>\n Physical properties:<\/strong> white powder, easily soluble in water<\/p>\n Chemical properties: <\/strong><\/p>\n Preparation<\/span><\/em><\/p>\n Boric acid can be prepared by reacting borax (sodium tetraborate decahydrate) with a mineral acid, such as hydrochloric acid:<\/p>\n Nature<\/span><\/em><\/p>\n Boric acid is soluble in boiling water. When heated above 170 \u00b0C, it splits into metaboric acid<\/i> (HBO 2<\/sub> ): <\/p>\n Metaboric acid is a white, cubic crystalline solid that is only slightly soluble in water. Boric acid melts at 236 \u00b0C, and when heated above 300 \u00b0C it further dehydrates to form tetraboric acid<\/i> or pyroboric acid<\/i> (H 2<\/sub> B 4<\/sub> O 7<\/sub> ): <\/p>\n The term boric acid<\/i> is also sometimes used to refer to these compounds. If further dehydrated, it produces boron trioxide<\/span> . <\/p>\n Boric acid does not dissociate in aqueous solvents<\/span> like Br\u00f8nsted acid<\/span> , but is a Lewis acid<\/span> that reacts with water molecules to form the tetrahydroxyborate<\/span> ion, and is observed under Raman spectroscopy<\/span> :<\/p>\n The polyborate anions produced form solutions with pH 7\u201310 if the boron concentration is greater than 0.025 mol\/L. The most common ion is tetraborate<\/i> found in the mineral borax:<\/p>\n Boric acid plays an important role in absorbing low frequency sound waves in seawater.<\/p>\n","protected":false},"excerpt":{"rendered":" Chemical formula: H3BO3 Chemical name: Boric Acid, Orthoboric Acid Origin: NBT Chemical Specification: 25 kg\/bag Physical properties: white powder, easily soluble …<\/p>\n","protected":false},"featured_media":1685,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[],"product_tag":[],"class_list":["post-1843","product","type-product","status-publish","has-post-thumbnail","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/vinachemistry.com\/ko\/wp-json\/wp\/v2\/product\/1843","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vinachemistry.com\/ko\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/vinachemistry.com\/ko\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/vinachemistry.com\/ko\/wp-json\/wp\/v2\/comments?post=1843"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vinachemistry.com\/ko\/wp-json\/wp\/v2\/media\/1685"}],"wp:attachment":[{"href":"https:\/\/vinachemistry.com\/ko\/wp-json\/wp\/v2\/media?parent=1843"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/vinachemistry.com\/ko\/wp-json\/wp\/v2\/product_brand?post=1843"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/vinachemistry.com\/ko\/wp-json\/wp\/v2\/product_cat?post=1843"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/vinachemistry.com\/ko\/wp-json\/wp\/v2\/product_tag?post=1843"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}\n
