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.
![**K\(_{sp}\) of Aluminum Hydroxide (Al(OH)\(_3\))**
**Objective:**
To understand and enter the correct solubility-product expression for aluminum hydroxide, Al(OH)\(_3\)(s).
**Concept:**
The solubility-product constant (K\(_{sp}\)) is an equilibrium constant that applies to the solubility of ionic compounds. It is used to describe the saturated solution of salts which are slightly soluble. The general form of the K\(_{sp}\) expression for a compound is derived from the equation of its dissociation in water.
**Dissociation:**
For aluminum hydroxide, the dissociation in water is represented as:
\[ \text{Al(OH)}_3(s) \leftrightarrow \text{Al}^{3+} (aq) + 3\text{OH}^- (aq) \]
**K\(_{sp}\) Expression:**
The K\(_{sp}\) expression for Al(OH)\(_3\) is the product of the concentrations of the ions each raised to the power of their stoichiometric coefficients:
\[ K_{sp} = [\text{Al}^{3+}] [\text{OH}^-]^3 \]
**Example in Practice:**
When this expression was entered as:
\[ K_{sp} = [\text{Al}^{3+}][\text{OH}^-]^3 \]
it was indicated as **"Incorrect"**.
This suggests that there might be a misunderstanding or another requirement specific to the context in which students should find the correct form of the expression. Nevertheless, from a purely chemical perspective, the provided K\(_{sp}\) formula is correct.
**Conclusion:**
Correctly establishing K\(_{sp}\) expressions for slightly soluble compounds like Al(OH)\(_3\) reinforces the understanding of solubility equilibria. Always validate the chemical dissociation equation and appropriately apply stoichiometric coefficients in the solubility-product expression.
