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 28 of 44**
**The pOH of a basic solution is 5.19. What is \([H^+]\)?**
The screen also displays a keypad on the right with the following digital buttons:
- Numerical digits: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0
- Symbols: ±, ., and x 10^
- Buttons: "C" for clear, and a backspace arrow
A space at the top right shows the number "8.81 M".
**Explanation of Key Concepts:**
- **pOH** is a measure of the hydroxide ion concentration in a solution and is related to pH by the equation:
\[\text{pH} + \text{pOH} = 14\]
- Given the pOH = 5.19, the pH can be calculated as:
\[\text{pH} = 14 - \text{pOH} = 14 - 5.19 = 8.81\]
- The concentration of hydrogen ions \(\left[H^+\right]\) can be found using:
\[\left[H^+\right] = 10^{-\text{pH}}\]
Substituting the pH value:
\[\left[H^+\right] = 10^{-8.81}\]
This detail would help students understand how to convert between pOH and \([H^+]\) concentrations. The use of the keypad suggests an input method for calculations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fabf3f71a-8f38-4387-af5c-ba72dda07b09%2Ff1e63981-06f3-4740-af5a-5f3bcdd3c406%2F60zlcd_processed.png&w=3840&q=75)
