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 ...

This economic and yield stability is key to resilience; it allows farmers to invest in soil fertility (e.g., composting) ...

We applied swim flume-mediated exercise during zebrafish caudal fin regeneration to explore mechanical loading impacts on a robust model of organ regeneration. Exercise initiated during but not after ...

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 ...

There is a growing push to expand pesticide buffer zones around schools — current regulations only require a 100-foot buffer, ...

Louisiana Wildlife and Fisheries Commission proposes reducing menhaden fishing buffer, sparking conflict between commercial ...
