Websigma bond, in chemistry, a mechanism by which two atoms are held together as the result of the forces operating between them and a pair of electrons regarded as shared by … WebAcetic acid is added to Gill type hematoxylins while citric acid is found in Mayers. The addition of acids to hematoxylin solutions increases the selectivity of the stain for nuclei by reducing nonspecific background staining. The effects of reduced pH on staining is discussed in greater detail in the section “Mechanism (s) of Staining”.
