Colorimetric Determination of the Hydrogen Ion Concentration in Small Quantities of Solution.*
نویسنده
چکیده
The hydrogen ion concentration (1) of many solutions and of culture media is readily determined by means of buffer solutions and suitable indicators. The usual procedure, in determining calorimetrically the hydrogen ion concentration, requires a considerable volume of solution. Frequently the quantity of solution available in experiments upon plants or animals is extremely limited in amount. It is of interest, therefore, to ascertain which modifications of the calorimetric method are best suited for the determination of the hydrogen ion concentration in small volumes of solution.
