What are the reaction types of metal ions in water?

Answer 1

Metal ions in water mainly have the following reaction types:
1. ** Sedimentation reaction **:
- Metal ions and many negative ions can form the precipitations of difficult dissolved substances. In addition to the simple precipitations reaction (such as\(Ag^++Cl^-\to AgCl\downarrow\), the formation and dissolution of many difficult dissolved substances are determined by the solute product\(K_{sp'). The formation and dissolution of many difficult dissolved substances are related to the pH of the solution, such as the precipitations of the acid, the precipitations of the weak acid salt, and the existence of the coordinating agent and the oxidiser.
- When metal ions reacted with an alkalium, they would form a hydrating ion in the solution. As a weak acid, the addition of the <> ion would cause the loss of the > ion, resulting in the formation of a solute. The final product was the uncharged trihydrating di-hydrogen oxid (simplified to ), which was usually a precipitation. Some of the precipitations could be further dissolved in excess base to become negatively charged complex ions, and some of the precipitations could be dissolved in hydrogen. The reaction of different metal ions with the solution of soda or the solution of water to form a solute was different. Except for the alkali-metal and barium-metal matrixes, most of the other matrixes were difficult to dissolve. Some metal matrixes (such as Be, Mn, and Al-metal) were amphobic, and their acidic nature was obvious. They were easy to dissolve in diluted strong bases, but different metal matrixes had different pH values when dissolved in bases.
- Alkali and alkali-earth metal sulphides are easily resolvable and will be strongly decomposed in solution. Sulfides of [Al^{3 +}],[Cr^{3 + }], and [Fe^{3 + }] will be completely decomposed in water to form a deposit of a hydrogen dioxide. Most of the other metal sulphides are hard to dissolve and most of them are colored.
2. ** Oxidation-reduction reaction **: The reaction types of metal elements in water solution can be divided into acid base reaction and oxidoreduction reaction. Oxidation-reduction reaction is a reaction in which electrons are transferred.
3. ** coordination reaction **: In the water environment, all metal ions exist as hydrating metal ions. In water, the complex reaction of this ion is a substitution reaction of the complex water molecules being replaced by other strong ligands.
4. ** Waterification reaction **: The corresponding salt of the metal element that makes up the amphobic solute (the salt of the acid) is easily waterlysable. The broad sense of the acid base reaction was a reaction that did not occur electron transfer, and the decomposition reaction belonged to the broad sense of the acid base reaction type.
5. ** Condensation reaction **: The broad sense of the acid base reaction is a reaction that does not occur electron transfer. Condensation reaction belongs to the broad sense of the acid base reaction type.
