Salivary amylase requires chloride ions for activation, but experimental results indicate a higher enzyme activity with KCl compared to NaCl. The discussion raises the possibility that the difference in enzyme rates could be related to the solvation properties of KCl versus NaCl, with a suggestion that KCl may dissociate more effectively in solution. There is also a recommendation to conduct an experiment using both KCl and NaCl together to determine if one of the salts negatively impacts the enzyme's reaction rate in either solution. This could provide further insight into the observed differences in enzyme activity.
