WebOct 25, 2024 · The most extreme example is hydrogen, where H + is a hard acid and H-is a soft base. Ni 3+ (as in the layered compound NiOOH) is a hard acid, but Ni 0 (as in Ni(CO) 4) is a soft acid. Nitrogen is hard when it is an ammine (-NH 2), but the nitrogen in pyridine is borderline due to increased polarizability imparted by the aromatic ring. The ... WebLesson 1: Acid/base equilibria.

Pearson some 30 years ago, has been used as a unifying principle in several texts. In spite of this, HSAB has remained qualitative and largely intuitive. In this article, the behaviour of HSAB in aqueous solution is addressed. A quantitative scale of hardness-softness for … fake cowgirl boots
