Thermometric titration

This method measures the temperature change caused by the heat of reaction that accompanies the reaction between the titrant and titrant, and determines the concentration of the desired chemical species in the titrant by determining the point at which no more temperature change remains as the endpoint of the titration. A highly sensitive thermistor thermometer is used to measure the temperature, and the reaction is carried out in a Dewar vessel. It is used, for example, when titrating a weak acid with a strong base.

滴定液と被滴定液の反応に伴う反応熱による温度変化を測定し，温度変化のなくなった点を滴定終点とし，被滴定液中の求める化学種の濃度を求める方法．温度測定は高感度サーミスター温度計を用い，反応はデュワー瓶中で行う．弱酸を強塩基で滴定する場合などに利用される．
