至于the basicity of acid的definition： refers to the number of replaceable hydrogen atoms in one molecule of the acid。如果你是用普通字典，或者计算机翻译，那绝对会翻译出碱 度之类的意思，但这也无可厚非，这是专业词汇的解释。其实不止国内，国外学生一开始接触这个概念绝对也会出错。以下引用...
What are examples of strong acids and strong bases? Strong acids include hydrochloric acid and sulfuric acid, while strong bases include sodium hydroxide and potassium hydroxide. 5 Share Your Discovery Share via Social Media Embed This Content Embed Code Share Directly via Messenger Link Previous ...
Evaluation of the basicity of sulfoxides by measurements of chemical shifts in aqueous sulfuric acidKinetic data demonstrates that the exchange of hydrogen at the 2-position of thiazolium ions cannot occur through the tetrahedral intermediate formed by nueleophilic addition of hydroxide to the 2-...
of hydrogen can react with dilute acids (HCl, H2SO4) in the order of activity of metals to produce hydrogen. The metal after hydrogen cannot react with dilute acids (HCl, H2SO4) but react with concentrated sulfuric acid and concentrated nitric acid. For example: 1 Cu2H2SO4 (concentrated...
In the case of sulfuric acid, a strong acid, the first proton is readily and completely ionized from the sulfuric acid molecule: HSO()+HO()HO()+HSO()2423+4–aqlaqaq However, the second proton in the product HSO4– only ionizes to a small extent. Thus, HSO4– is a weak acid: HSO...
An acid-base reaction is the sharing of an electron pair with an acid by a base. These three simple definitions constitute the heart of what is now known as the Lewis concept of acids and bases.Experimentally and conceptually, they are an extension of the Brønsted definitions. In one broa...
