當前位置:首頁 >產品中心 >高純氣體

名稱:高純氫氣

氫氣是無色無味的氣體,標準狀況下密度是0.09克/升(最輕的氣體),難溶于水。在-252 ℃,變成無色液體,-259 ℃時變為雪花狀固體。襄陽高純氫氣,襄陽氣體,襄陽氫氣價格,歡迎到中原海咨詢。
詳情介紹

 氫氣是無色無味的氣體,標準狀況下密度是0.09克/升(最輕的氣體),難溶于水。在-252 ℃,變成無色液體,-259 ℃時變為雪花狀固體。襄陽高純氫氣,襄陽氣體,襄陽氫氣價格,歡迎到中原海咨詢。

氫氣化學性質
氫氣常溫下性質穩定,在點燃或加熱的條件下能多跟許多物質發生化學反應。
①可燃性(可在氧氣中或氯氣中燃燒):2H2+O2=點燃=2H2O(化合反應)
(點燃不純的氫氣要發生爆炸,點燃氫氣前必須驗純,相似的,氘(重氫)在氧氣中點燃可以生成重水(D2O))
H2+Cl2=點燃=2HCl(化合反應)
H2+F2=2HF(氫氣與氟氣混合立刻爆炸,生成氟化氫氣體)
②還原性(使某些金屬氧化物還原)
H2+CuO  Cu+H2O(置換反應)
3H2+Fe2O3=高溫=2Fe+3H2O(置換反應)
3H2+WO3  W+3H2O(置換反應)
