名称被你打错了!应该是CH3COONa,乙酸钠,又名醋酸钠,是强碱弱酸盐,乙酸钠就是它的全称!它是乙酸(CH3COOH)和氢氧化钠(NaOH)酸碱中和反应的产物.
Therefore, if a reaction starts with an acid that donates its proton, one of the products will be the conjugate base of that acid. Answer and Explanation: 1 Become a Study.com member to unlock this answer! Create your account View this answer Sod...
NA代表阿伏加德罗常数,下列说法正确的是( ) A. 含有NA个CH3COO-的醋酸溶液中氢离子数为NA B. 3.65g液态HCl中构成的粒子总数为0.2NA C. 常温下5.6gFe投入足量浓硝酸中,则转移电子数为0.3NA D. 常温常压下,30g乙酸与30g葡萄糖含有的氧原子数均为NA ...
A strong acid/base is one that ionizes completely in water, meaning that all of the molecules dissociate into ions. In contrast, a weak acid/base only partially dissociates in water. This can be seen in the equilibrium expression, where a strong acid/base has a larger equilibrium constant ...
【题目】醋酸镍((CH3COO)2Ni]是一种重要的化工原料。一种以含镍废料(含NiS、Al2O3、FeO、CaO、SiO2)为原料,制取醋酸镍的工艺流程图如下: 相关离子生成氢氧化物的pH和相关物质的溶解性如下表: (1)粉碎含镍废料的作用___ (2)酸浸过程中,l molNiS失去6NA个电子,同时生成...
1下列各组离子在溶液中能大量共存的是( )①Ca2+、Na+、OH—、NO3— ②K+、Fe3+ I—、Cl— ③NH4+、Na+、Cl—、CH3COO—④K+、Mg2+、SO42—、CO32- ⑤Na+、S2—、SO42—、H+ ⑥Na+、Cl—、ClO—、SO42— A. ①②...
下列电离方程式书写正确的是( ) A. Na3PO4=3Na++ B. Ba(OH)2=Ba2++ C. CH3COOH=CH3COO-+H+ D. NaHCO3=Na
解:A、醋酸是弱电解质,电离方程式为CH3COOH⇌CH3COO-+H+,故A错误; B、氢氧化钠能完全电离,电离方程式为NaOH═Na++OH-,故B正确; C、氯酸钾是强电解质,能完全电离出钾离子和氯酸根离子,即电离方程式为KClO3═K++ClO3-,故C错误; D、硫酸钡是强电解质,硫酸根离子团不能拆开,电离方程式为BaSO4═Ba2++SO...
下列电离方程式中,正确的是() A. CH3COOH = CH3COO-+ H+ B. KClO3K++ ClO3- C. NaOH = Na++ OH- D. NaHS
This is distinct from a weak acid or weak conjugate base solution by itself, which would have a much larger molarity ratio of the two weak species. The buffer solution maintains such a ratio so that it can be effective against the addition...
