The paper is a dissertation paper that describes analysis of pH in diluted bicarbonate solutions using different partial pressures of CO_{2}. In the work, an equation was obtained from the balance equations of a base-bicarbonate-water system. Similarly, an equation was obtained to describe the relationship of partial pressure of CO_{2} and hydrogen ion concentration of a bicarbonate solution. This equation can be used to determine the bicarbonate concentration of a gas mixture.
