Hydrogen-ion concentration--Measurement; Lead; Acetates
It shall be the object of this investigation to measure the hydrogen ion concentration in lead acetate solutions and to apply the measurements to the control of color in the preparation of chrome yellow pigments. Lead acetate solutions of high concentration, known as lead liquors, are used in the preparation of chrome yellows by precipitation with sodium dichromate. Since the color of the pigment is believed to be dependent on the hydrogen ion concentration of the lead acetate solution used, such a study is of interest to dry-color manufacturers and to users of chrome yellows. The methods now in use for the analysis of lead acetate are to be reviewed, and an attempt will be made to measure the hydrogen ion concentration of the lead acetate solutions by a potentiometric method. It is proposed, therefore, to measure the hydrogen ion concentration in the lead acetate solutions, and to show the effect of hydrogen ion concentration on the color of chrome yellow pigments.
