Calculate the solubility (in moles per liter) of Fe(OH)3 (Ksp = 4 × 10¬38) in each of the following. a. water Solubility = mol/L b. a solution buffered at pH = 6.0 Solubility = mol/L c. a solution buffered at pH = 10.0 Solubility = mol/L
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:**
Calculate the solubility (in moles per liter) of Fe(OH)₃ \((K_{sp} = 4 \times 10^{-38})\) in each of the following environments:
a. **Water**
Solubility = ______ mol/L
b. **A solution buffered at pH = 6.0**
Solubility = ______ mol/L
c. **A solution buffered at pH = 10.0**
Solubility = ______ mol/L
**Instructions for Calculation:**
To solve these problems, you will need to consider the solubility product constant (\(K_{sp}\)) expression for iron (III) hydroxide, \(\text{Fe(OH)}_3\), which is:
\[ K_{sp} = [\text{Fe}^{3+}][\text{OH}^-]^3 \]
Using the given \(K_{sp}\) value and understanding the effect of pH on \([\text{OH}^-]\) concentration, calculate the solubility in different scenarios.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3216a391-9091-4165-86c6-f10847a236cf%2F785281a2-46ad-47c3-a006-22cef84060da%2F58wwkn8_processed.png&w=3840&q=75)
