At 25 °C, what is the hydroxide ion concentration, [OH¯], in an aqueous solution with a hydrogen ion concentration of H+]-2.9 х 10-9 M? [OH"] = 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.
![### Determining Hydroxide Ion Concentration
**Question:**
At 25 °C, what is the hydroxide ion concentration, \([OH^-]\), in an aqueous solution with a hydrogen ion concentration of \([H^+]=2.9 \times 10^{-9}\) M?
**Solution:**
To find the hydroxide ion concentration, \([OH^-]\), we can use the relationship between the concentrations of hydrogen ions (\([H^+]\)) and hydroxide ions (\([OH^-]\)) for water at 25 °C. The product of these concentrations is the ion-product constant for water (\(K_w\)):
\[ K_w = [H^+][OH^-] = 1.0 \times 10^{-14} \]
Given:
\[ [H^+] = 2.9 \times 10^{-9} \, \text{M} \]
We can rearrange the equation to solve for \([OH^-]\):
\[ [OH^-] = \frac{K_w}{[H^+]} \]
Substitute the given values:
\[ [OH^-] = \frac{1.0 \times 10^{-14}}{2.9 \times 10^{-9}} \]
Perform the calculation:
\[ [OH^-] = \frac{1.0 \times 10^{-14}}{2.9 \times 10^{-9}} = 3.45 \times 10^{-6} \, \text{M} \]
**Answer:**
\[ \mathbf{[OH^-] = 3.45 \times 10^{-6} \, M} \]
