How to control the liquid flow in the burette of acid-base neutralization titration? Explain both, one is a glass piston and the other is rubber. ...

The glass piston is called an acid burette. It controls the flow of liquid through the glass piston. There is a small hole in the glass piston. Rotate the piston, adjust the area of the small opening and control the liquid flow. The one with rubber tube is called alkaline burette, which controls the flow rate by squeezing the glass ball in the rubber tube and forming a cavity between the tubes.
