化學反應是化學中非常基礎和重要的概念,除了酸鹼反應,還有以下幾種反應:

氧化還原反應:氧化還原反應是指一種化學反應,其中電子從一個分子轉移到另一個分子,產生氧化物和還原物。在這種反應中,原子的氧化態會發生改變。

酸鹼中和反應:酸鹼中和反應已經在問題中提到過,這是指酸和鹼的反應,其中產生水和一種稱為鹽的化合物。

沉澱反應:沉澱反應是指當兩種溶液混合時,其中一種或多種化學物質形成不可溶的沉澱物質。這種反應可以用來分離和分析不同的化學物質。

雙水解反應:雙水解反應是指一種化學反應,其中一種化合物被水分子分解成兩個分子,同時另一種化合物被水分子結合形成一個新的分子。

酯化反應:酯化反應是指酸和醇反應生成酯的過程。酯是一種常見的有機化合物,廣泛存在於天然和合成的物質中,例如油脂和香料等

People might relate entropy and disorder but these are different concepts. One way to think of entropy is via a probability distribution. If I am concerned with heat capacity/stability, I can think about the number of different vibrations that can be stimulated by energy. If I am concerned with reactions, I can think of the different states I can transmit through the TS or the "width" of my TS.

Bonds don’t store energy, the atoms/molecules/functional groups involved in it do.
