According to the Lewis theory of acids and bases an acid is a proton donor and a base is a proton acceptor. 这句话对不对? 还是应该according to Bronsted Lowry theory ? 急用 谢谢~~ 相关知识点: 试题来源: 解析 应该是后一种 According to Bronsted Lowry theory.原因是:布朗特(Bronsted)的酸碱...
A base is a substance that neutralizes an acid. A base which is soluble in water is called an alkali. 碱就是能中和酸的物质。注意base和alkali的区别。 另一种定义: A Bronsted-Lowry acid is a proton donor. 酸就是能提供氢离子(即质子)的物质。 A Bronsted-Lowry base is a proton acceptor....

We also compared the CTF-TF with the CTF-TF-0.5 that is synthesized by adjusting the proportion of monomers. The surface area of CTF-TF-0.5 is close to that of CTF-TF (401.3 m2g−1vs. 407.7 m2g−1) (Supplementary Fig.16), however, the proton conductivity of H3PO4@CTF-TF-0.5...

Compound 32 will then react with a molecule of liberated water in the presence of the NEt3 base to yield the more nucleophilic boronate complex 33, which we propose as the resting state of the organoboron catalyst. In the rate-limiting step, the reaction between the resting states 30a and ...

D is a highly electronegative donor atom covalently attached to the H atom. A is an acceptor atom with a full or partial negative charge, lone pair of electrons, or another electronegative feature (such as an adjacent pi bond) directed towards the H atom. Hydrogen bonds are usually represente...
