A saturated solution of nickel(II) hydroxide, Ni(OH)2, has a pH of 9.5. What is the hydronium ion concentration of the solution? Is the solution acidic or basic? Concentration = The solution is - M
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.
![### Nickel(II) Hydroxide Solution Analysis
A saturated solution of nickel(II) hydroxide, \( \text{Ni(OH)}_2 \), has a pH of 9.5. This exercise involves finding the hydronium ion concentration of the solution and determining if the solution is acidic or basic.
#### Required Calculations:
1. **Hydronium Ion Concentration (\( \text{H}_3\text{O}^+ \))**:
- The concentration of hydronium ions can be calculated using the formula:
\[
\text{pH} = -\log[\text{H}_3\text{O}^+]
\]
- Rearranging provides:
\[
[\text{H}_3\text{O}^+] = 10^{-\text{pH}}
\]
2. **Concentration**:
\[
\text{Concentration} = \, \_\_\_ \, \text{M}
\]
#### Solution Acidity:
- **Determination**: The solution is classified by its pH value:
- Neutral: \( \text{pH} = 7 \)
- Acidic: \( \text{pH} < 7 \)
- Basic: \( \text{pH} > 7 \)
The solution is **basic** given the pH of 9.5.
