Which of the following apparatus is
used in determination of molecular
weight of the polymer?
O Potentiometer
O Stalagmometer
O Ostwald viscometer
O Conductometer
Answers
Answer:
Potentiometer is the answer, I think it will he the correct answer
None of the above
Potentiometer:
A position sensor is a sort of potentiometer. It is used to determine how far something has moved in any direction.
Stalgmometer:
A stalagmometer is a basic, manual instrument. It is used for measuring liquid surface tension and, less frequently, the interfacial tension between two liquids.
Ostwald viscometer:
Ostwald viscometer is also known as the U-tube viscometer. It is a device that is used to determine the viscosity of a liquid of known density.
Conductometer:
The quantity of electrical current or conductance in a solution is measured by a conductivity meter.
Size-exclusion chromatography is used to determine the molecular weight of the polymer.
Therefore, none of the given options are used in the determination of the molecular weight of the polymer.
