Hard acids
Mandarin:
硬酸 (yìng suān)
硬酸 (yìng suān)
Explanation in English Language (EN):
In the context of Lewis acid-base theory, hard acids are Lewis acids that are small, highly charged, and have low polarizability. They tend to form strong bonds with hard bases, which are Lewis bases with similar characteristics. Examples of hard acids include metal ions like Al3+ and Fe3+. Hard acids can be used as catalysts in certain polymerization reactions.

Explanation in Mandarin (ZH):
在路易斯酸碱理论中，硬酸是体积小、电荷高、极化率低的 Lewis 酸。它们倾向于与硬碱形成强键，硬碱是具有相似特征的路易斯碱。硬酸的例子包括像 Al3+ 和 Fe3+ 这样的金属离子。硬酸可用作某些聚合反应的催化剂。
