\nAn ammonium buffer solution typically consists of a weak base, ammonium hydroxide (NH₄OH), and its conjugate acid, ammonium chloride (NH₄Cl). This type of buffer can help maintain a stable pH in a solution, usually around pH 9 to 11, making it useful in various biological and chemical applications. \n

Components of Ammonium Buffer Solution:

\n

\n
• Ammonium Hydroxide (NH₄OH): The weak base.
\n
• Ammonium Chloride (NH₄Cl): The salt provides the conjugate acid.
\n

\n

Preparation:

\n

\n
1. Mix Solutions: Combine a certain volume of ammonium hydroxide with a known concentration of ammonium chloride.
\n
2. Adjust pH: Use a pH meter to ensure the solution is at the desired pH; adjust if necessary by adding more acid or base.
\n
3. Dilute: Add distilled water to achieve the desired final volume.
\n

\n

Function:

\nThe buffer works by neutralizing small amounts of added acid or base. When an acid (H⁺ ions) is added, the NH₄⁺ ions from NH₄Cl react with it to form NH₄OH, while added bases are neutralized by NH₄OH. \n

General Applications of Ammonium Buffer Solution:

\n

\n
• Biological experiments (e.g., enzyme assays)
\n
• Analytical chemistry (e.g., maintaining pH in titrations)
\n
• Biochemical assays and protocols
