This lab includes a theoretical explanation of how buffers work and how they are made, including a derivation of the Henderson-Hasselbalch equation. Students will use what they have learned to ...

Two types of acid-base titration stand out: alkalimetry and acidimetry. Each method provides a precise means to measure compounds based on their acid or basic content, depending on the type of the ...

Plastic polypropylene vials showed minimal BAK adsorption loss, outperforming glass vials, including premium and silanized types. Benzalkonium chloride (BAK) is a common preservative composed of ...

So, if the concentration of hydrogen ions exceeds 1 mole per liter, as in a 12 M hydrochloric acid solution, the calculated ...

A chemical buffer is a solution that can resist changes in pH when small amounts of acid or base are added. Generally, biological compounds with ionizable groups with a pKa around 8 exhibit buffering ...

The soybean is a protein source of high biological value. However, the presence of anti-nutritional factors affects its protein quality and limits the bioavailability of other nutrients. The effect of ...
