HYDRANAL-Buffer for Acids is a buffer solution used in Karl Fischer titration, specifically for acid titrations. This solution helps maintain a stable pH during titration, which is essential for accurate and reproducible reactions. The buffer typically contains an organic base that neutralizes acids produced during the Karl Fischer reaction.
Karl Fischer Titration:
A volumetric analytical technique used to determine the water content in various samples.
Buffer:
A solution containing a weak acid and its conjugate base (or vice versa) that can resist changes in pH when small amounts of acid or base are added.
HYDRANAL:
A trademark for a range of Karl Fischer titration reagents manufactured by Honeywell Research Chemicals.
Buffer for Acids:
In the context of Karl Fischer titration, this buffer is important because some substances being titrated may be acidic, and their reactions can produce hydrogen ions that affect the readings. The buffer helps maintain a stable pH, ensuring titration accuracy.
Common Components:
Buffers for acids typically contain organic bases, such as imidazole or other bases, which can neutralize the acids generated during titration.
