Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.

![### Understanding Lewis Acids and Bases
In the given reaction, trimethylborane (\( B(CH_3)_3 \)) reacts with dimethyl ether (\( (CH_3)_2O \)) to form an ether complexed borane.
#### Reaction Overview:
1. **Reactants:**
- **Trimethylborane (\( B(CH_3)_3 \))**: This molecule has an electron-deficient boron atom.
- **Dimethyl ether (\( (CH_3)_2O \))**: This molecule has a lone pair of electrons on the oxygen atom.
2. **Product:**
- **Ether complexed borane**: The oxygen in dimethyl ether donates its lone pair of electrons to the boron in trimethylborane, forming a coordinate covalent bond. This changes the structure and charge arrangement of the molecules involved.
**Diagram Description:**
The diagram shows the electron-pair donation from dimethyl ether to trimethylborane. An arrow indicates this movement of electrons. In the product, the oxygen in dimethyl ether is coordinated to boron, forming a complex.
#### Questions:
1. **Lewis acid of the reaction above is:**
\[ \boxed{\text{Trimethylborane} \hspace{8pt} (B(CH_3)_3)} \]
**Explanation:**
A Lewis acid is a molecule that can accept an electron pair. In this reaction, the boron atom in trimethylborane accepts a pair of electrons from the oxygen in dimethyl ether.
2. **Lewis base of the reaction above is:**
\[ \boxed{\text{Dimethyl ether} \hspace{8pt} ((CH_3)_2O)} \]
**Explanation:**
A Lewis base is a molecule that can donate an electron pair. In this reaction, the oxygen atom in dimethyl ether donates a pair of electrons to the boron in trimethylborane.
This reaction is a classic example of Lewis acid-base interaction, where the Lewis base donates electrons to the Lewis acid, forming a new chemical complex.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa7f9c6ce-7c61-4a7b-90a0-6a641d198bf8%2F7fde8b32-3d14-4e5b-8c9c-d536e369c1a2%2Fs8i9cwk_processed.png&w=3840&q=75)
