想問下alcohol嘅acidic / alkaline / oxidiZing property會唔會考?
同埋點比較HCOOH / CH3COOH嘅acidity/pH?
THX 問題少年
咩叫alcohol既alkaline property
你指係用strong acid,e.g HI哩d格硬protonate個alcohol?e.g alcohol變CH3OH2+
Bxxxx-lowry alkali唔係解proton receptor 咩
咁Alcohol都算係呀...?
梗係唔係啦
DSE根本都唔係用bronsted lowry definition
所以呢個就係我成日講
考試大忌就係特登拋d程度高過syllabus既出黎
因為中學同大學個理解根本唔同
依家中學考試 夾硬同大學chem果套去講
好多時愈講愈亂
而且 嚴格黎講DSE有自己個acid definition:
A hydrogen containing compound, when dissolved in water, can produce H+ ion as the only cation.
呢個定義同Arrhenius / bronsted lowry / lewis 三大acid base definition都有出入
可以話係Arrhenius definition基礎上再加特定條件
sorry呀我見到佢打d acidity果d我以為佢唔係dse,所以我個comment都用咗off topic個emoji 真係唔好意思 我自隊一打膠 sorry
唔係話你啦
討論chem係一定會涉及到out syl野
唔係話out syl就唔好提 始終知識係無所謂既syllabus
最緊要個前題係要識分 syllabus既要求 同埋 實際理解 既分別
兩者好多時未必對等
