Under high ionic strength conditions, high electrolyte concentrations may accelerate the reaction rate in ion–neutral molecular reactions by forming an association or ion pair as a new activation center36. The energy barrier of these intermediate products might be influenced by temperature changes, ...
Na2SO4Strong ElectrolytesStrong electrolytes are compounds that can dissolve in an aqueous solution to form anions and cations. The strength of the electrolyte can be predicted by checking the solubility rules of ionic compounds in w...
TheLeAMT1.1andLeAMT1.2, the two important high-affinity NH4+transporters, were reported to have contrasting responses:LeAMT1.1was induced by N deficiency thoughLeAMT1.2was increased by an NH4+or NO3−supply [20]. WhileLeAMT1.2-mRNA levels in a concentration-dependent manner were controlled by NH4...
The strongly alkaline carrier electrolyte based on DEA employed throughout this work provided sufficient separation of the investigated analytes from peaks related to the sample matrix. Various kinds of soybean milk samples were successfully analyzed using optimized acid hydrolysis followed by the CE ...

Define an electrolyte. Define electrolyte and non-electrolyte. What is the definition of a strong electrolyte? Give some examples. Is CaI2 classified as a strong electrolyte? Explain. What does it mean to describe the charge distribution of a molecule?
CaCl2 K2CO3 HCl (NH4)2CO3 D. NaNO3 Na2SO4 HCl H2SO4 答案 [答案]B[解析][解答]解:A、溶液呈蓝色的为硫酸铜溶液,但是本组物质中两两之间均不能反应,所以不能鉴别出,故A错; B、溶液呈黄色的为氯化铁溶液,可以和氯化铁反应生成红褐色沉淀的为氢氧化钠;而能够将氢氧化钠和氯化铁溶液反应生成的沉淀...
