摘要
A method for the automatic, electro-chemical determination of the end point of titration utilizing an initial, continuous addition of the titrant, up to a predetermined value, followed by a step-by-step addition with a resting time inserted therebetween for stabilization of the solution is disclosed. As the titrant is being added to the bath sample in constant volume units, a measured value is formed after every such addition. The difference to the preceding measurement is determined and the three consecutive differences of greatest magnitude are utilized in a mathematical formula for calculating the end point. The titration ceases when the greatest difference lies between two lesser values.
