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:**
What is the pH of 0.89 M lithium acetate at 25°C? The ionization constant \( K_a = 1.96 \times 10^{-5} \). (Type in your answer to 3 significant figures)
**Guidance:**
To calculate the pH, consider the following steps:
1. **Dissociation Equation:**
Write the dissociation equation for lithium acetate in water and identify it as a weak acid.
2. **Expression for \( K_a \):**
Use the expression for the acid dissociation constant to set up the equation:
\[
K_a = \frac{[H^+][A^-]}{[HA]}
\]
3. **Assumption for Weak Acids:**
Assume that the change in concentration of the acid (\([HA]\)) due to dissociation is negligible compared to its initial concentration.
4. **Solve for [H⁺]:**
Use the equilibrium expression to determine the \([H^+]\).
5. **Calculate pH:**
Determine the pH using the formula:
\[
\text{pH} = -\log[H^+]
\]
Ensure the answer is typed to three significant figures as requested.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0d520b33-7440-45bc-bf50-9535ed2d03bc%2Ff9d650f6-1558-4393-9672-1cdd3e7a64cd%2Flewl76c_processed.jpeg&w=3840&q=75)
