The researchers bisulfated the polymer to improve its solubility for spectroscopy.

The research team synthesized several bisulfates to analyze their solubility in organic solvents.

During the titration of sulfuric acid, bisulfate acts as a weak acid and affects the equivalence point.

When exposed to the acid solution, the amine will bisulfate, forming a stable salt.

To lower the pool's pH quickly, the maintenance team added a measured amount of sodium bisulfate.
