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.

### Titration Problem: Determining the pH of a Solution
**Problem Statement:**
What is the pH of the solution when 50.0 mL of 0.20 M HI is titrated with 40.0 mL of 0.139 M Sr(OH)₂?
**Chemical Equation:**
\[ 2 \text{HI} + \text{Sr(OH)}_2 \rightarrow \text{SrI}_2 + 2 \text{H}_2\text{O} \]
**Solution Calculation:**
\[ \text{pH} = \boxed{\ ?\ } \]
**Hint:**
Be careful of the mole ratios!
**Interactive Component:**
Below is an input field for you to provide the pH after considering the reaction and calculations:
\[ \text{pH at 40.0 mL base:} \underline{\hspace{150px}} \ \text{Enter} \]
**Detailed Explanation of Diagram:**
The diagram features a balanced chemical equation, showing that two moles of Hydrogen Iodide (HI) react with one mole of Strontium Hydroxide \(\text{Sr(OH)}_2\) to produce one mole of Strontium Iodide (\(\text{SrI}_2\)) and two moles of water (\(\text{H}_2\text{O}\)).

**Steps to Calculate the pH:**
1. **Calculate moles of HI and Sr(OH)₂:**
- Moles of HI: \( M \times V = 0.20 \, \text{M} \times 0.050 \, \text{L} = 0.010 \, \text{moles} \)
- Moles of Sr(OH)₂: \( M \times V = 0.139 \, \text{M} \times 0.040 \, \text{L} = 0.00556 \, \text{moles} \)
2. **Determine the limiting reagent:**
- 2 moles of HI react with 1 mole of Sr(OH)₂
- We need twice the moles of HI compared to Sr(OH)₂, i.e., 0.01112 moles of HI are required to react with 0](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4f25db15-46c0-4416-96ae-dcfe4c7f9271%2F3bfea114-5c34-4c3f-bb32-b77dc256089d%2F1y1qrc_processed.jpeg&w=3840&q=75)
