Aluminum Cation | Al+3 | CID 104727 - PubChem
2021年10月14日 — Aluminium(3+) is an aluminium cation that has a charge of +3. It is an aluminium cation, a monoatomic trication and a monoatomic aluminium.
Aluminium - Wikipedia
The aluminium cation Al 3+ is small and highly charged; as such, it has more polarizing power, and bonds formed by aluminium have a more covalent character. The strong affinity of aluminium for oxygen leads to the common occurrence of its oxides in nature.
Aluminum Cation - an overview | ScienceDirect Topics
An Aluminum Cation is a positively charged aluminum ion that is part of a cationic aluminum complex used as a polymerization catalyst for epoxides in chemistry. It is electron deficient, facilitating the activation of epoxides through coordination, leading to the production of polyethers with varying molecular weights.
Cations and Anions: Definitions, Examples, and Differences
2020年3月3日 — Cations and anions are the two types of ions. Ions have an imbalance of electrical charge, meaning they contain different numbers of protons and electrons. Cation have a positive electrical charge and have more protons than electrons. Anions have a negative electrical charge and have more electrons than protons.
Aluminium compounds - Wikipedia
In aqueous solution, Al 3+ exists as the hexaaqua cation [Al (H 2 O) 6] 3+, which has an approximate pK a of 10 −5. [13] . Such solutions are acidic as this cation can act as a proton donor, progressively hydrolysing to [Al (H 2 O) 5 (OH)] 2+, [Al (H 2 O) 4 (OH) 2] +, and so on.

Chemistry Terms: Table of Common Cations - ThoughtCo
2019年11月4日 — Cations are ions which have a positive electrical charge. A cation has fewer electrons than protons. An ion may consist of a single atom of an element (a monatomic ion or monatomic cation or anion) or of several atoms that are bonded together (a polyatomic ion or polyatomic cation or anion).
Aluminum (III) Cations [ (NHC) ⋅ AlMes - Wiley Online Library
2023年10月25日 — Rare examples of three-coordinate aluminum cations of the form [ (NHC) ⋅ AlMes 2] + [B (C 6 F 5) 4] − and their etherate analogues [ (NHC) ⋅ AlMes 2 (OEt 2 )] + [B (C 6 F 5) 4] − are presented. The Lewis -acidity of the cations was evaluated theoretically and experimentally to be very high.
Characteristic Reactions of Aluminum Ions (Al³⁺)
2023年8月29日 — Characteristics: Silvery, rather soft. Very active, but protected by an oxide coating. Aluminum ion reacts with aqueous ammonia to produce a white gelatinous precipitate of Al (OH)3: Al3 + (aq) + 3NH 3(aq) + 3H 2O(aq) − ⇀ ↽ − Al(OH) 3(s) + 3NH + 4 (aq)
