濃硫酸與發煙硫酸的區別-營口盛?；び邢薰?/title> <meta name="keywords" content="發煙硫酸" /> <meta name="description" content="1、意思不同：發煙硫酸發煙硫酸，也就是三氧化硫的硫酸溶液。無色至淺棕色粘稠發煙液體，其密度、熔點、沸點因SO3含量不同而異。當它暴露于空氣中時，揮發出來的SO3和空氣中的水蒸氣形成硫酸的細小露滴而冒煙，所以稱之為發煙硫酸。濃硫酸，俗稱壞水，..." /> <link rel="shortcut icon" type="image/x-icon"

2em;">濃硫酸，俗稱壞水，化學分子式為H?SO?，是一種具有高腐蝕性的強礦物酸。濃硫酸指質量分數大于或等于70%的硫酸溶液。</p><p style="text-align: center;"><img src="/data/upload/image/20161228/1482923670506951.jpg" alt="發煙硫酸" width="600" height="600"

2em;">對有機物的腐蝕發煙硫酸更強；對金屬的腐蝕濃度低的硫酸更強。</p><p><br/></p><p style="text-indent: 2em;">3、性質不同：</p><p><br/></p><p style="text-indent: 2em;">濃硫酸：含有大量未電離的硫酸分子（強酸溶液中的酸分子不一定全部電離成離子，酸的強弱是相對的），所以濃硫酸具有吸水性、脫水性（俗稱炭化，即腐蝕性）和強氧化性等特殊性質；而在稀硫酸中，硫酸分子已經完全電離，所以不具有濃硫酸的特殊化學性質。</p><p><br/></p><p style="text-indent: 2em;">發煙硫酸：無色或棕色油狀稠厚的發煙液體（棕色是因為其中含有少量鐵離子），具有強烈刺激性臭味，吸水性很強，與水可以任何比例混合，并放出大量稀釋熱。所以進行稀釋濃硫酸的操作時，應將濃硫酸沿容器壁慢慢注入水中，并不斷用玻璃棒攪拌。</p><p><br/></p></div> <h3 class="tag">相關標簽：<a
