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
![**Title: Effect of Complex Ion Formation on Solubility**
**Introduction:**
The formation of complex ions can significantly impact the solubility of otherwise insoluble compounds. Here, we explore the solubility behavior of silver chloride (AgCl) in the presence of cyanide ions (CN⁻).
**Experiment Overview:**
Consider the insoluble compound **silver chloride, AgCl**. The silver ion (Ag⁺) forms a complex with **cyanide ions** (CN⁻). The net ionic equation for this reaction reveals why the solubility of AgCl(s) increases when cyanide is present. To understand this interaction, we'll calculate the equilibrium constant for the reaction using provided solubility product constant data.
**Chemical Reaction:**
The complex ion formed is **Ag(CN)₂⁻** with a formation constant \( K_f = 1.3 \times 10^{21} \).
- Start with Ag⁺ ions, which can be sourced from the dissociation of AgCl.
- The cyanide ions will interact with the Ag⁺ to form the complex ion.
**Net Ionic Equation:**
\[ \text{AgCl(s)} + 2 \text{CN}^- \rightarrow \text{Ag(CN)}_2^- + \text{Cl}^- \]
*Be sure to specify the states of each reactant and product, such as (aq) for aqueous or (s) for solid.*
**Equilibrium Constant, \( K \):**
To calculate the equilibrium constant (\( K \)), you'll need to integrate the solubility product constant of the initial compound with the formation constant of the complex ion.
**Summary:**
Understanding the effect of complex ion formation on solubility can provide insights into dissolution processes, and how certain ions can enhance the solubility of materials otherwise considered insoluble. This knowledge is critical in various chemical applications and industries.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4126b89b-6ee3-437f-8fcf-aa0e90855818%2F754a4b1f-5b3f-44dc-9ab2-df051b4f4d76%2Fijrfai_processed.jpeg&w=3840&q=75)
