<p>　　鹽酸是化學(xué)工業(yè)重要原料之一，廣泛用于化工原料、染料、醫藥、食品、印染、皮革、制糖、冶金等行業(yè)。還用于離子交換樹(shù)脂的再生以及電鍍、金屬表面的清洗劑<br /> 　　物理性質(zhì)<br /> 　　與實(shí)驗室鹽酸相比，工業(yè)鹽酸顏色偏黃。因為工業(yè)用鹽酸一般是用氯氣在氫氣中燃燒生成氯化氫，然后將生成的氯化氫用水吸收得到的。合成氯化氫的時(shí)候會(huì )使用一種特殊的燃燒管，此管由2個(gè)同心鋼管（鋼是鐵的合金）組成，內管導入氯氣，外管導入氫氣。由于此管為鐵合金，而氯氣具強氧化性，因此在生成氯化氫的同時(shí)，鋼管中的鐵也和氯氣反應生成了氯化鐵，該物質(zhì)溶于水后會(huì )使溶液顯黃色。<br /> 　　化學(xué)性質(zhì)<br /> 　　純鹽酸為無(wú)色有刺激性臭味的液體，當有雜質(zhì)時(shí)呈微黃色。有強烈的腐蝕性，揮發(fā)性：濃鹽酸在空氣中發(fā)煙，觸及氨蒸汽會(huì )生成白色云霧。吸水性：不具有吸水性。其氣體對動(dòng)植物有害，鹽酸是強無(wú)機酸，對皮膚或纖維均有腐蝕作用，能與很多金屬起化學(xué)反應生成金屬氯化物并放出氫。與金屬氧化物、堿反應生成鹽和水。鹽酸屬二級無(wú)機酸性腐蝕物品，危規編號93001。</p> </div> <div id="i86uf1e" class="page"> <p><a
