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.

Question

1. For the following compounds, write the conjugate base that would result if the labeled proton were removed. Include resonance structures if there are any. Indicate which of the two labeled protons you expect to be more acidic and why.

a) A compound with two labeled protons \(H_a\) and \(H_b\). The structure includes an alkene and an alkyne.

b) A compound featuring a benzene ring attached to an ester group, with labeled protons \(H_a\) on the oxygen and \(H_b\) on the ethoxy group.

c) A structure containing an imine with \(H_a\) on the carbon attached to nitrogen and \(H_b\) on the nitrogen itself.

d) A diketone structure with \(H_a\) and \(H_b\) on the carbon adjacent to the ketone groups.

### Analysis:

- **a)** More acidic proton likely depends on hybridization (alkyne \(H_b\) is often more acidic due to sp hybridization).
- **b)** Consider resonance stabilization for \(H_a\) (phenoxide ion) vs. \(H_b\); typically \(H_a\) is more acidic because of resonance.
- **c)** Imine nitrogen proton \(H_b\) may have different acidity due to resonance or electron-withdrawing effects from nitrogen.
- **d)** \(H_b\) near carbonyl groups might be more acidic because of resonance and inductive effects.
