『壹』 什么是两性离子

既能和酸反应,又能和碱反应的叫两性离子
比如HCO3-
HCO3- + H+ =H2O+CO2
HCO3- + 0H-=H20+CO3 2-

『贰』 什么是两性离子

一些离子既能电离出氢离子,又能结合氢离子,称为两性离子。
如碳酸氢根离子 亚硫酸氢根离子 磷酸氢根离子 磷酸二氢根离子 氢硫酸氢根离子。

『叁』 什么是阴离子,阳离子,非离子,两性离子

原子失去电子显正价,变成阳离子(一般多为金属)。原子得去电子显负价,变成阴离子(一般多为非金属)。离子即可以和阳离子反应,也可以和阴离子反应的为两性离子(如Al3+)

『肆』 ( 两性离子表面活性剂;发展趋势;农药制剂;油脂基表面活性剂;特种表面活性剂;化妆品)怎样用英语翻译

zwitterionics surfacant, development tendency,PesticidesFormulation,oil-based surfacant, Special surfactant, Cosmetics

『伍』 氨基酸的缩写符号

氨基酸的缩写符号是AA,英文全称:amino acid。

氨基酸为无色晶体,熔点超过200℃,比一般有机化合物的熔点高很多。α一氨基酸有酸、甜、苦、鲜4种不同味感。谷氨酸单钠盐和甘氨酸是用量最大的鲜味调味料。

氨基酸一般易溶于水、酸溶液和碱溶液中,不溶或微溶于乙醇或乙醚等有机溶剂。氨基酸在水中的溶解度差别很大,例如酪氨酸的溶解度最小,25℃时,100 g水中酪氨酸仅溶解0.045 g,但在热水巾酪氨酸的溶解度较大。赖氨酸和精氨酸常以盐酸盐的形式存在,因为它们极易溶于水,因潮解而难以制得结晶 。

各种常见的氨基酸易成为无色结晶,结晶形状因氨基酸的结构不同而有所差异。如L一谷氨酸为四角柱形结晶,D一谷氨酸则为菱形片状结晶。

(5)两性离子英语怎么说及的英文翻译扩展阅读

氨基酸在水溶液或结晶内基本上均以兼性离子或偶极离子的形式存在。所谓两性离子是指在同一个氨基酸分子上带有能释放出质子的NH3+缬氨酸离子和能接受质子的COO-负离子,因此氨基酸是两性电解质。

氨基酸的等电点:氨基酸的带电状况取决于所处环境的pH值,改变pH值可以使氨基酸带正电荷或负电荷,也可使它处于正负电荷数相等,即净电荷为零的两性离子状态。使氨基酸所带正负电荷数相等即净电荷为零时的溶液pH值称为该氨基酸的等电点。

氨基酸分子中同时含有酸性基团和碱性基团,因此,氨基酸既能和较强的酸反应。也能与较强的碱反应而生成稳定的盐,具有两性化合物的特征。

当调节某一种氨基酸溶液的pH为一定值时,该种氨基酸刚好以偶极离子形式存在,在电场中,既不向负极移动,也不向正极移动,即此时其所带的正、负电荷数相等,净电荷为零,呈电中性,此时此溶液的pH称为该氨基酸的等电点(isoelectric point),通常用pI表示。

在等电点时,氨基酸主要以偶极离子的形式存在。当氨基酸溶液的pH大于pI时(如加入碱),氨基酸中的一NH3+给出质子,平衡右移,这时氨基酸主要以阴离子形式存在,若在电场中,则向正极移动。反之,当溶液的pH小于pI时(如加入酸),氨基酸中的一COO-结合质子,使平衡左移,这时氨基酸主要以阳离子形式存在,若在电场中,则向负极移动。

『陆』 英语翻译

First, the anion polyacrylamide [proct application] 1, mainly serves as the flocculant: Regarding suspended particle, thick, density high, grain of innertube positive charge, water PH value for neutrality or alkalinity sewage, because in the anion polyacrylamide member chain includes the ration polar group to be able in the absorbed water the aerosol solids, causes between the granule the bridging to form big flocculating.Therefore it accelerates in the suspending liquid granule subsidence, has extremely obviously speeds up the solution clarifying, effects and so on promotion filtration. 2nd, uses in the oil instry, the extraction, the drilling mud, the waste mud conditioning, prevented the water breakthrough, reces the frictional resistance, enhances the recovery ratio, three extractions obtains the widespread utilization.3rd, other professions.If food profession, paper instry, textile instry and so on. Second, the positive ion polyacrylamide positive ion polyacrylamide presents the electropositivity in acidity or in the alkalinity medium, it usually can is lower than the anion or the non-ionic polyacrylamide molecular weight, its clear clean sewage performance mainly is obtains through the electric charge neutralization.This kind of flocculant function mainly is the flocculation belt negative electric charge, has eliminates, the decolorization function muddy. Third, amphion polyacrylamide proct shape: The amphion polyacrylamide (ACPAM) outward appearance is the white silt. Proct characteristic: The amphion polyacrylamide because of the molecular content positive ion base and the anion base, it has had outside the common positive ion flocculant handling characteristics, has displayed a more outstanding performance. Amphion certainly not anion, positive ion mix.If can occur the positive ion polyacrylamide and the anion polyacrylamide coordination use the response to proce the precipitation.Therefore the amphion proct is most ideal. Main use: The oil field accent splits the blocking agent, with the crosslinking agent, the stabilizer, the ulant agent joint action, the proction has the important polymerization gelatin and the resin gelatin excel in congeals the medicinal preparation rubber blocking agent.It through attaches, function jamming stratum holes and the crack and so on physical jamming, the adjustment proportion, may control the gelatin time, adapts the different geological clear situation.Each kind of greasy dirt, organic, inorganic, sewage, complex sewage processing.Does not decide in the PH change in sewage system.Uses in the sludge dewatering. The lignin polyacrylamide chemistry accent split the medicinal preparation the research and the application, the paper summarizes the water-injection well chemistry accent to split medicinal preparation the type and the application condition, in this foundation, split the medicinal preparation to the lignin polyacrylamide accent to carry on the development and the appraisal. The laboratory experiment indicated that, this kind of accent splits when the medicinal preparation best matches the front army 1 synthesis main body medicinal preparation PS mother liquor, the polyacrylamide PAM best increment is 0.6%, the lignin Ca-LS best increment is when 1.05% configuration accents split the medicinal preparation liquid cement, the PS mother liquor dilutes 10 times, the potassium bichromate best increment is 0.6%, the thiourea best increment is 0.4%. under this allocated proportion. The accent splits the medicinal preparation the gelatin intensity to be bigger than 100000mPa.s, becomes the rubber time to indicate at the 20~60h adjustable core sample experiment, the jamming rate is bigger than 99%, the breakthrough pressure is bigger than 0.5MPacm, the core sample microscopic image indicated, the gelatin jamming core sample original big passageway, behind the force water round jamming area, forms new side to flow the channel, enhanced the flood water to affect the coefficient. The field application indicated that, after chemistry accent splits, the water-injection well injection profile was improved, connect the oil well to split obviously the effect sub-area chemistry accent indicated, the water-injection well high absorbing water layer and thickness rece, absorbed water lowly the layer and thickness increases, slowed down the sub-area declining proction rate and the watery ascending velocity, has realized the sub-area mining effect improvement.只供参考,不一定是的,还要请高手看一下才行

『柒』 两性离子的英文怎么写

『玖』 离子的英语翻译 离子用英语怎么说

『拾』 离子价态英语怎么读 比如: 二价铜; 三价铁; 负一价Cl ;负二价的Cl 请各位大侠帮忙。。。。谢谢!

一般离子价态在口语里能让人听懂就行了,越简单越好,比如:
Ru2+可以读成Ru positive 2

S2- 读成S minus 2

大家都能理解。

比较正规的就用专门的名词,比如:
亚铜离子:cuprous ion,monovalent copper ion
铜离子:cupric ion,bivalent copper ion
三价:trivalent

四价:tetravalent
五:pentavalent;六:hexavalent。。。。依次类推(跟有机物命名类似)。

当然也可以用长一点的:
copper with +1 oxidation state /valence state /valence number
copper with +2 oxidation state /valence state /valence number
