Experimental Procedure. Asch used a lab experiment to study conformity, whereby 50 male students from Swarthmore College in the USA participated in a 'vision test.' There were 18 trials in total, and the confederates gave the wrong answer on 12 trails (called the critical trials).Introduction In this experiment a mixture of two acids is titrated with standard base. Because the pH does not change abruptly enough at either equivalence point to permit estimation with visual indicators, a potentiometric titration with a pH meter and glass pH electrode-reference electrode pair is employed.
