Which is the primary fixative component of B-5 fixative?

Explanation:
Mercuric chloride is the active fixative in B-5. In this prepare, mercuric chloride reacts with tissue proteins to form stable cross-links that preserve structure. The acetic acid helps with penetration and nuclear detail, while water simply serves as the solvent and sodium acetate functions as a buffer in some formulations. Formaldehyde is used in other fixatives (like formalin) but is not the primary fixative component in B-5.
