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.
![**Instructions for Curved Arrow Pushing Mechanism:**
To fully demonstrate the mechanism for this chemical reaction:
1. **Add Non-bonding Electrons and C-H Bonds:**
Ensure all relevant line-angle structures include non-bonding electrons and C-H bonds.
2. **Identify Lewis Acids and Bases:**
At each step, specify the Lewis acid (LA) and Lewis base (LB). Also, indicate if they function as Brønsted acids or bases (LA/BA, LB/BB).
3. **Number of Steps:**
Provide the total number of steps in the mechanism.
**Chemical Reaction Scheme:**
- **Reactants:**
- The starting material features an ether group (OMe) and is indicated with a lone pair on the oxygen atom.
- Excess lithium aluminum hydride (LiAlH₄) is shown, with the bond structures explicitly drawn, and Li⁺ separated.
- **Products:**
- The primary product depicted has an oxygen atom with a negative charge and an attached lithium cation (Li⁺), showing added hydrogen atoms (C-H) next to the carbon.
- A secondary product is lithium methoxide, Li⁺ with an OMe group bearing a negative charge.

A Lewis acid is a species that accepts electrons. It is positively charged or has vacant orbitals to accept electrons.
A Lewis base donates electrons. It is having negative charge or lone pair of electrons to donate.
A bronsted lowry acid donates protons while a bronsted lowry base accepts protons.
LiAlH4 is a very strong reducing agent, used to reduce almost all carbonyl derivatives. With ester it reacts to give corresponding alcohol, One equivalent of LiAlH4 can reduce two equivalents of ester. Aprotic solvents are required to carry out these reactions.
