Good afternoon​

Answer 1

Answer:

Cationic Lewis Acids

Metal cations have two characteristics that allow them to act as Lewis acids:

1. Their positive charge attracts electrons.

2. They have at least one empty orbital that can accomodate an electron pair.

When a metal cation encounters a substance with a lone electron pair, a coordination compound can form. An example of this is when metal ions are in an aqueous solution they are hydrated (or they form a coordination compound with water). The metal ion is a Lewis acid; water is a Lewis base.

Cationic Lewis Acids

Cationic Lewis AcidsMetal cations have two characteristics that allow them to act as Lewis acids:

1)Their positive charge attracts electrons.

2) They have at least one empty orbital that can accomodate an electron pair.

When a metal cation encounters a substance with a lone electron pair, a coordination compound can form. An example of this is when metal ions are in an aqueous solution they are hydrated (or they form a coordination compound with water). The metal ion is a Lewis acid; water is a Lewis base.

There are many substances that have lone electron pairs, making them potential Lewis bases when combined with metal cations.

One Lewis base that deserves special mention is hydroxide (OH-). The hydroxide ion binds easily to many metal ions forming metal hydroxides. Some metal hydroxides are amphiprotic (or are able to act as an acid or a base). Their amphiprotic nature allows solid metal hydroxides to dissolve when either an acid or base is added.
