✦ Synopsis
The tltrlmetnc method for the determmatlon of total baslclty and avadable lysme residues m protemaceous samples m anhydrous acetlc acid has been Improved by replacmg potentlometrlc tltratlons by visual tltratlons The agreement between the expenmental tltratlon curve obtamed from protemaceous samples and both experlmental and theoretIca curves for pure lysme was tested The composttlon of a sultable screened mdlcator accordmg to the acldlty of the tltratlon equivalence range was calculated
The experlmental results agree with the potentlometrlc results
