    SODIUM. SODIUM. Sodium is normally present in food and in the body in its ionic (charged) form rather than as metallic sodium. Sodium is a positively charged ion or cation (Na +), and it forms salts with a variety of negatively charged ions (anions).Table salt or sodium chloride (NaCl) is an example of a sodium salt. In solution, NaCl dissociates into its ions, Na + and Cl-.

    What Is the Purpose of Salt in DNA Extraction

    When mixed in an alcohol solution, the sodium component of NaCl provides a protective barrier around the negatively-charged DNA phosphate ends, enabling them to move closer to be extracted out of the solution. DNA extraction is the process of obtaining pure DNA from a sample, either from living or non-living cells, such as those found in viruses.

    Recrystallization and Acid/Base Extraction The Basics

    Explanation of A/B (acid base) extraction. Most drugs have an amine group. This is a -NH 2 attached to the molecule somewhere. NH 3 is a base (accepts protons from acids easily) so the drugs are bases also. Hence the name freebase. When you make the drug, it usually starts out in the freebase form, which is quite often an oil.
