There is no unified equation for calculating titration error in the textbook of analytical chemistry. The Ringbom's equation is the most frequently used, but the equation has problems. This work made a theoretic analysis of the Ringbom's equation based on the definition of titration error. The results show that the calculated end point error using Ringbom's formula is different from that based on the definition. We believe this work can provide fundamental basis for the establishment of reasonable titration error calculation.

Key words: End point error, Ringbom's formula
