ชุดทดลองการหามวลโมลาร์โดยการวัดระดับความสูงของจุดเดือด ( อิบูลลิโอสโคป)

Principle

Didactic setup to train and demonstrate the determination of molar masses by way of a measurement of the boiling point elevation. The boiling point elevation of aqueous solutions of different substances is determined using. The ebullioscopic constant of water is calculated from the experimental results.

Benefits

Compact, easily transportable setup

Experimentation made easy by intuitive operation

For both demonstration and student experiments
