Comments:
Since the inhibitor contains some NH4Cl, control experiment was performed with 10 wt % NH4Cl added to a benzamidinium chloride solution at the usual concentration. Within error, the thermodynamic parameters were identical. Therefore, the concentration of inhibitor, based on weight, can be safely corrected for the amount of NH4Cl present.
