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
![**Determine the pH of the Titration**
*Objective*: Calculate the pH at the point in the titration of 40.0 mL of 0.200 M HC₄H₇O₂ with 0.100 M Sr(OH)₂ after 10.0 mL of the strong base has been added. Given that the \(K_a\) for HC₄H₇O₂ is \(1.5 \times 10^{-5}\).
**Titration Details:**
- \(K_a\) Expression Setup:
You are required to set up the expression for \(K_a\) based on your ICE table and definition. Avoid combining or simplifying terms.
**Equation Provided:**
\[
K_a = \frac{[0.0400 - x][x]}{0.0200 - x} = 1.5 \times 10^{-5}
\]
**Feedback Message (Incorrect Response):**
- You have an incorrect expression for \(K_a\). Recall the general definition of \(K_a\) for the generic acid \(HA\) as indicated:
\[
HA(aq) + H_2O(l) \rightarrow H_3O^+(aq) + A^-(aq)
\]
\[
K_a = \frac{[H_3O^+][A^-]}{[HA]}
\]
**Note**: You have 1 attempt remaining to correct the expression.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faeef920a-b7fc-42c4-a405-16f92aebf3b1%2Fd904b3a5-ffbf-4f33-944c-733fbec1c26e%2Fnzr4f8_processed.jpeg&w=3840&q=75)
