NH4HCO3可以治疗胃酸过多否?
发现一种简单的制F2的方法,求鉴定 原料是MnO2和HF MnO2+4HF==MnF4+2H2O 控制MnO2过量,防止被配位成MnF62- 然后把水弄掉,加热……
有做过HSO3F的吗? RT,如果硫酸加HF这一招行吗?
P2O5是脱水之王?
什么情况下硝酸能出氢气? 据有人说硝酸能出氢气。求鉴定
化吧什么时候被封过?
硼能显负价吗? rt,如果能,最多是-3还是-5?
复杂阴离子电解到底会在阳极生成什么? 硫酸根、硝酸根、碳酸根、氢氧根、卤素含氧酸根、这些电解会在阳极生成什么? 哪里有没有一张这样的表?
酸化的KMnO4可以溶Au? Au3+电极电势1.4,MnO4-电极电势1.5…… 求高手鉴定。。。
问大家一个问题:liu suan mei rong ma?
大家有没有觉得碱一直都是酸的陪衬 对于身边物体的腐蚀,酸总是大于碱。酸能腐蚀金属,碱只能腐蚀少量AlZn等金属。(其实我把Zn放NaOH里加热,什么反应都没有)。碱对非金属的腐蚀也很牵强。。。只能对Cl2这种活泼的起作用。硫粉放NaOH里加热磷事都没有。。人家硝酸吃碳吃磷不比吃金属差多少。。。王水连木头都能吃一点。。王水和硫酸都能吃橡胶。。玻璃有HF在。OH-吃玻璃很慢。。总之酸还有强氧化性,强酸酸酐里元素都是高氧化值的。。而强碱碱酐里元素都是低氧化值的,氧化不了谁。。碱也不能还原,除非和F2反应。而酸里H2S和HI都是强还原性酸。。酸中有很多强酸,彼此由于酸根不同而个性各异。。比如硫酸脱水,HCN强络合,硝酸强氧化,还有HF怪胎一个。三大强酸彼此区别非常大。而三大强碱NaOH、KOH、Ba(OH)2感觉基本没有区别。。。酸都是液体,基本上都溶。碱不溶的就一大堆。。。化尸用的都是酸,没人用碱。你看街上泼人用的都是H2SO4或者HF,哪个用过NaOH?
突然发现王水很BT 今天配了一点,发现除了玻璃以外基本上什么东西进去都要冒气泡 扔固态烧碱进去,水可以直接沸腾 铜丝进去也很快
氮能否形成类似白磷的N4分子?
C+2H2==CH4,条件是? RT,从标准摩尔生成H上来看,还是放热的反映……
有没有Ca2C这种东西?
CN-是最强的路易斯碱?
一氧化碳剧毒是因为它络合能力强吗?
[转]F2与金属的反应 稍微翻译了一点,重要内容都翻译了。 常温下Na和K就能与F2激烈反应。 Ca也能在F2中燃烧。产生的热量使活泼金属熔化、红热。 镁粉也很容易燃烧。 还原铁粉在低温下就能与F2反应,生成白色氟化物。 Al、Cr、Mn在F2中加热到红热时可以燃烧,发出绚丽的光彩。 Zn在F2中稍微加热就燃烧,非常好看。 锑在常温下就与F2反应,生成白色氟化物。(貌似是3价的,要是5价的就牛了……) Pb与Hg在低温下就反应,非常迅速。 Cu在加热到稍微红热就反应,生成的氟化物甚至能继续氟化成过氟化物(!!!!很想知道这个的结构)。 Ag在常温下缓慢腐蚀,加热到100摄氏度时逐渐生成黄颜色氟化银。 Au稍微加热就生成黄颜色的氟化金,但再加热一下氟化金就要分解。 Pt在低温与F2反应,100度时反而不反应。但600度时会燃烧起来。 Sodium and potassium combine with fluorine with great vigor at ordinary temperatures, becoming incandescent, and forming their respective fluorides, which may be obtained crystallized from water in cubes. Metallic calcium also burns in fluorine gas, forming the fused fluoride, and occasionally minute crystals of fluorspar. Thallium is rapidly converted to fluoride at ordinary temperatures, the temperature rising until the metal melts and finally becomes red hot. Powdered magnesium burns with great brilliancy. Iron, reduced by hydrogen, combines in the cold with immediate incandescence, and formation of an anhydrous, readily soluble, white fluoride. Aluminum, on heating to low redness, gives a very beautiful luminosity, as do also chromium and manganese. The combustion of slightly warmed zinc in fluorine is particularly pretty as an experiment, the flame being of a most dazzling whiteness. Antimony takes fire at the ordinary temperature, and forms a solid white fluoride. Lead and mercury are attacked in the cold, as previously described, the latter with great rapidity. Copper reacts at low redness, but in a strangely feeble manner, and the white fumes formed appear to combine with a further quantity of fluorine to form a perfluoride. The main product is a volatile white fluoride. Silver is only slowly attacked in the cold. When heated, however, to 100°, the metal commences to be covered with a yellow coat of anhydrous fluoride, and on heating to low redness combination occurs, with incandescence, and the resulting fluoride becomes fused, and afterward presents a satin-like aspect. Gold becomes converted into a yellow deliquescent volatile fluoride when heated to low redness, and at a slightly higher temperature the fluoride is dissociated into metallic gold and fluorine gas. The action of fluorine on platinum has been studied with special care. It is evident, in view of the corrosion of the positive platinum terminal of the electrolysis apparatus, that nascent fluorine rapidly attacks platinum at a temperature of -23°. At 100°, however, fluorine gas appears to be without action on platinum. At 500°-600° it is attacked strongly, with formation of the tetrafluoride. PtF, and a small quantity of the protofluoride, PtF. If the fluorine is admixed with vapor of hydrofluoric acid, the reaction is much more vigorous, as if a fluorhydrate of the tetrafluoride, perhaps 2HF.PtF, were formed. The tetrafluoride is generally found in the form of deep-red fused masses, or small yellow crystals resembling those of anhydrous platinum chloride. The salt is volatile and very hygroscopic. Its behavior with water is peculiar. With a small quantity of water a brownish yellow solution is formed, which, however, in a very short time becomes warm and the fluoride decomposes; platinic hydrate is precipitated, and free hydrofluoric acid remains in solution. If the quantity of water is greater, the solution may be preserved for some minutes without decomposition. If the liquid is boiled, it decomposes instantly. At a red heat platinic fluoride decomposes into metallic platinum and fluorine, which is evolved in the free state. This reaction can therefore be employed as a ready means of preparing fluorine, the fluoride only requiring to be heated rapidly to redness in a platinum tube closed at one end, when crystallized silicon held at the open end will be found to immediately take fire in the escaping fluorine. The best mode of obtaining the fluoride of platinum for this purpose is to heat a bundle of platinum wires to low redness in the fluorspar reaction tube in a rapid stream of fluorine. As soon as sufficient fluoride is formed on the wires, they are transferred to a well stoppered dry glass tube, until required for the preparation of fluorine.
已知最强氧化剂是F2?
pH值的下限是-11.8,有证明 最小的H+就是氕+,就是质子,直径为1.6 * 10 -15次方米 而如果把大量H+压到一起(不考虑H+之间巨大的排斥力),那么一升的体积最多可以容纳的H+数量为1 * 10 -3 / (1.6 * 10 -15)= 6 * 10的11次方。 即氢离子浓度为6*10的11次方。 pH=-log(6*10的11次方)=-11.8
今天又建了被T了还在里面的情况 被T了,居然还在里面,可惜一开始就跳了应该是传输文件导致的
