Question

What is Landolt's experiment?

Answer 1

The motive of Landolt's experiment:

• The experiment of Landolt is used to define the "law of conservation of mass."
• According to the law of conservation of mass, mass cannot be generated or destroyed in a chemical or physical process or transition.

Landolt's experiment:

• In this experiment, an H-shaped tube constructed specifically for this technique is used.
• $\mathrm{NaCl}$ and ${\mathrm{AgNO}}_3$ were weighed in a U-shaped tube in Landolt's experiment.
• The tubes were slanted to allow the liquids to mix and react.
• They were weighed again, and the weight remained the same.
• This is the definition of the law of conservation of mass, which asserts that mass in an isolated system is not generated or destroyed by chemical reactions or physical changes. Hence law of conservation of mass is proved using Landolt's experiment.
