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.
![### Problem Statement:
**15.0 mL of 4.0 M HCl is added to 85.0 mL of water. What is the final concentration of the acid?**
**Calculate the final concentration:**
The final concentration is expressed in mol/L, represented by the following:
[ ? ] mol / L \( \text{HCl} \)
Below the problem statement, there is a blank field labeled "M HCl" where the solution can be entered, followed by an "Enter" button to submit the answer.
### Explanation:
To find the final concentration of the HCl solution, you can use the dilution formula:
\[ C_1V_1 = C_2V_2 \]
where:
- \( C_1 \) is the initial concentration (4.0 M)
- \( V_1 \) is the initial volume (15.0 mL)
- \( C_2 \) is the final concentration
- \( V_2 \) is the final volume
Since the final volume \( V_2 \) is the sum of the initial volume of HCl and the volume of water added:
\[ V_2 = 15.0 \, \text{mL} + 85.0 \, \text{mL} = 100.0 \, \text{mL} \]
Rearranging the dilution formula to solve for \( C_2 \):
\[ C_2 = \frac{C_1 V_1}{V_2} = \frac{(4.0 \, \text{M})(15.0 \, \text{mL})}{100.0 \, \text{mL}} \]
\[ C_2 = \frac{60.0 \, \text{M} \cdot \text{mL}}{100.0 \, \text{mL}} \]
\[ C_2 = 0.6 \, \text{M} \]
So, the final concentration of the acid is 0.6 M HCl.
You can enter the calculated final concentration (0.6 M) in the provided field and click the "Enter" button to submit your answer.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0e0dd2c8-2c2b-4452-a4b7-24696070e6a2%2F4498e8aa-3ad8-4b39-8cf2-765c2d14a512%2Ftkkn89_processed.jpeg&w=3840&q=75)
