Which acid is present in paper?
Wood pulp paper from before the 1980s also tends to be acidic from alum-rosin sizing (added to the paper to reduce absorbency and minimize bleeding of inks), which, in the presence of moisture, generates sulfuric acid. Acids also form in paper by the absorption of pollutants — mainly sulfur and nitrogen oxides.
How is paper made chemically?
In order to have paper, chemistry must be put to use. The main ways chemistry is used in creating paper is when the lignin is dissolved in the water and taken from the cellulose. The next way chemistry is used is when the fibrils from the cellulose bond together to form a compact structure called paper.
