HCl的化學名稱是什麽？HCl的化學性質？

返回打印发布时间：2023/6/25 点击：12767

HCl的化學名稱是什麽：

1、氯化氫，化学式为HCl，氯化氫分子由一个氯原子和一个氢原子组成，是一种无色气体，有刺激性气味。其水溶液俗称盐酸，学名盐酸。氯化氫极易溶于水。0℃时，1体积的水可溶解约500体积的氯化氫。

2、氯化氫主要用于制造染料、香料、药物、各种氯化物和缓蚀剂。

HCl的化學性質：

1、能与酸碱指示剂发生反应。遇紫色石蕊试液，石蕊会变红色，遇无色酚酞，冲泡后不变色。

2、能与活泼金属（迁移率领先于氢的金属）发生反应。如与镁、铝、锌、铁反应。

3、能与碱发生反应。如氢氧化钠、氢氧化钙的反应。

4、能与金属氧化物发生反应。如氧化钙、氧化铁等。

5、与某些盐发生反应。如碳酸盐（如碳酸钠、碳酸钙）、硝酸银反应。

氯化氫物理性质：

氯化氫无色，熔点-114.2度，沸点-85度。有窒息性气味，对上呼吸道有强烈刺激，对眼睛、皮肤、粘膜有腐蚀作用。比空气密度大，其水溶液为盐酸，浓盐酸易挥发。摩尔质量36.4606g/mol，外观无色吸湿性气体，密度1.477g/L(25°C)(气体)。相对密度(水=1)1.19，相对蒸气密度(空气=1)1.27，熔点158.8K(-114.2°C)，沸点187.9K(-85°C)，溶解度(水)72g/100mL(20°C)(标准压力)，饱和蒸气压(kPa)4225.6(20°C)。

什么是氯化氫？

氯化氫是一种无色气体，有刺激性气味。浓盐酸是无色液体，将其放入瓶子中，过一会儿，瓶口处会出现白雾（由于盐酸的挥发性较强，白雾是盐酸产生的小液滴）由氯化氫挥发与空气中的水蒸气化合而成，有刺鼻的酸臭味。

工业盐酸因含有铁盐杂质，会呈淡黄色。它很容易溶于水。0℃时，1体积的水可溶解约500体积的氯化氫。氯化氫的水溶液呈酸性，称为盐酸，属于强酸，习惯上称为盐酸。主要用于制备染料、香料、药物、各种氯化物和缓蚀剂。盐酸是氯化氫hcl的水溶液，無色或微黃色液體，易揮發。

Then suddenly all surmise and speculation was expunged from his mind, for no longer the clack of the typewriting machine came from next door. He heard the stir of a chair pushed back, and the rattle of a door handle. Norah was coming; who was of greater concern than all his thoughts about her.... And he was going to give her no quarter: she would have to introduce the subject of her feelings with regard to his niggardly hospital-subscription herself. He knew something of her pride from the affair of the book-plate, and he longed to see her take that armour off. "Found anything out, mate?" another officer asked. It is not intended to recommend writing down rules or tables relating to shop manipulation so much as facts which require remark or comment to impress them on the memory; writing notes not only assists in committing the subjects to memory, but cultivates a power of composing technical descriptions, a very necessary part of an engineering education. Specifications for engineering work are a most difficult kind of composition and may be made long, tedious, and irrelevant, or concise and lucid. From a quite small garden close to the palace a bronze gate with three medallions of lilies in high relief, of marvellous workmanship, opens on the Pearl Mosque, exquisitely white, at the end of its forecourt of immaculate pavement enclosed by a marble balustrade. Three polished and shining domes are supported by columns of snow made of a hard white marble, scarcely broken by [Pg 218]ornament, and carrying a roof hollowed into three vaults. The rings are still to be seen on the marble walls outside, to which, when the great Mogul came to prayer, curtains were attached made of gold net and spangled with diamonds and pearls. Sandy’s birthday dawned hot, but clear, with a good, steady south wind blowing. “Jeff calls it a ‘jinx’—a ‘hoodoo’,” responded Dick. “But the chef would discover it—they couldn’t be left there!” She was sitting in her room, sewing. Of late she had become domesticated, and she was fading under it. He had seen it already, and he saw it more plainly than ever just now. She looked up and smiled. Her smile had always been one of her greatest charms, because it was rare and very sweet. "Jack," she greeted him, "what have you done with the bread knife you took with you, dear? I have been lost without it." "Neither," drawled Cairness. "But Mrs. Lawton, here, has been good enough to tell me that you have known the exact truth about the Kirby massacre ever since a week after its occurrence, and yet you have shielded the criminals and lied in the papers. Then, too," he went on, "though there is no real proof against you, and you undoubtedly did handle it very well, I know that it was you that set Lawton on to try and bribe for the beef contract. You see your friends are unsafe, Mr. Stone, and I have been around yours and Lawton's ranches enough to have picked up a few damaging facts." The prince found in the Opposition in England the most unfortunate fosterers of his unfilial temper. Pulteney, Wyndham, Chesterfield, Carteret, Cobham, and, worst of all, Bolingbroke, became his associates, and the frequenters of his house. Fast ripening into a pattern of unfilial popularity under such influences, possessing some accomplishments, and a desire to stand well with the people, he married in April, 1736, Augusta of Saxe-Gotha, a princess of so much beauty and good sense, as might have reclaimed many a nature; who seems to have at least won the heart of her husband from his former romantic passion. It was an ominous circumstance, however, that the address of congratulation on this occasion was moved, not by the king's own Ministers, but by the king's own Opposition. Pulteney was the mover, and it was supported by two young men who that evening made their first speeches, and in them burst suddenly forth with that splendour which was destined to grow transcendent through many years. They were Pitt, afterwards Lord Chatham, and Lord Lyttelton. The Deacon had just remembered that he had not seen that individual for some little time, and looked around for him with some concern. It was well that he did. Shorty had come across the haversack that the Deacon had brought, and it awakened all his old predatory instincts, sharpened, if anything, by his feebleness. Without saying a word to any body, he had employed the time while the Surgeon and Deacon were in conversation in preparing one of his customary gorges after a long, hard march. He nearly succeeded. There was silence, in which a coal fell. She still stood with her arms outstretched; he knew that she was calling him—as no woman had ever called him—with all that of herself which was in his heart, part of his own being. "Why, my lord," said Luke, in reply to De Boteler's interrogatory, "there is hardly a free maiden in the parish that would not have been glad of Stephen; but, though I have never seen her, I am told this wife of his is the comeliest damsel between this and Winchcombe: and, besides, she is not like a common nief—and then, my lord, she is the sister of the good monk John."
