该测定法是根据它们在水中溶解度的不同而进行的。(苯巴比妥几乎不溶于冷水,而巴比妥则能溶于170份冷水中——译者注)一、苯巴比妥与巴比妥的总滴定:精密称取一定量的粉末溶,解于3Oml,10%结晶碳酸钠溶液中,用0.1N 硝酸银溶液滴定至微呈混
The assays are based on their solubility in water. (Phenobarbital almost insoluble in cold water, and barbiturate can dissolve in 170 cold water - a note, the total titration of phenobarbital and barbital: accurately weighed amount of powder , Solution in 3Oml, 10% crystalline sodium carbonate solution, titration with 0.1N silver nitrate solution to slightly mixed
