The properties of most acids, especially in water solutions, arise from the hydrogen ion (H+, also referred to as the hydronium ion, H3O+, the form in which H+ is found in a water environment).

大多数酸尤其是在水溶液中的酸，其各种性质都是因存在氢离子(H+，亦可产生水合氢离子H3O+，因此任何水的环境都可发现氢离子)而产生的。

The properties of most acids, especially in water solut ion s, arise from the hydrogen ion (H+, also referred to as the hydronium ion , H3O+, the form in which H+ is found in a water environment).

In a large test tube, dissolve 0.5 g (4.5 mmole) of semicarbazide hydrochloride and 0.5 g of anhydrous sodium acetate (or 0.8 g of sodium acetate trihydrate) in 4 mL of distilled water and 7 mL of ethanol.

在一个大试管中，用4 mL蒸馏水和7 mL乙醇溶解 0.5 g (4.5 mmole)的胺基氢氯酸盐和0.5 g无水醋酸钠(或0.8 g的三水合醋酸钠)。

It can be assumed that, the Mg~(2+) ions remain as hydrated ion forms when adsorbed onto micellar surface because of its strong hydration effect, so it can not neutralize the micellar surface charge effectively, make it destabilized and flocculated, neither can it form low-solubility salt with SDS as in SDS-CaCl_2 system.

认为是由于Mg~(2+)离子的水合作用比较强，导致其以水合离子的形式在胶束表面吸附，未能有效地接近并中和胶束表面电荷，也未能像Ca~(2+)那样，与SDS形成难溶盐而结晶沉淀。

It was found that not only are χ Al 2O 3 and η Al 2O 3 capable of rehydration,but also all the above mentioned transitional aluminas can be rehydrated when in contact with H 2O under its saturation pressure at temp...

结果表明，上述诸脱水产物均可发生再水合现象，最终的转化产物均是薄水铝石，而非它们的原起始物。

Their technology and process is basically similar to that used ethylene, the raw material for the oxygen in the silver catalyst, caused by methane or nitrogen stabilizer, the existence of inhibitors of chloride, ethylene oxide directly generate ethylene oxide and ethylene B N and further to certain substances in water than in the tubular reactor for generating hydration ethylene glycol, ethylene glycol solution through evaporation to mention thick, dehydration, fractionation be ethylene glycol and other by-products.

它们的工艺技术和工艺流程基本上相似，即采用乙烯、氧气为原料，在银催化剂、甲烷或氮气致稳剂、氯化物抑制剂存在下，乙烯直接氧化生成环氧乙烷，环氧乙烷进一步与水以一定物质的量比在管式反应器内进行水合反应生成乙二醇，乙二醇溶液经蒸发提浓、脱水、分馏得到乙二醇及其他副产品。
