Although formaldehyde is a weak acid (pK greater than 13), there was no riced to estimate and correct the base bound by formaldehyde, because the base bound by wool was always determined by comparing the base present at equilibrium in aliquots of tn-o solutions identical except for the fact that one contained wool and …
What is advantage and disadvantage of formaldehyde?
Formaldehyde is widely used fixative. Its advantages are low cost, simplicity of use and good fixation traits, which are fast tissue penetration, good preservation of morphological structures and compatibility with downstream histological applications. Formaldehyde disadvantages are negative effects on nucleic acids.

Which is more acidic formaldehyde or acetic acid?
But in acetic acid, its conjugate base, i.e. acetate anion has a methyl group. It has the ability to destabilize the negative charge on the oxygen. Hence we can say that formic acid is more acidic than acetic acid.
Is formaldehyde a Lewis acid?
Usually, HCN is a Brønsted acid or a Lewis base,16 while FCN is a Lewis base. Here, the complex obtained for HCHO−FCN exhibits the strong amphoteric character of FCN, which can act as both a Lewis base and a Lewis acid.
