Question
State the main points of Landolt’s experiment for experimental evidence of the law.
Solution
Main points of Landolt's experiment
- In an 'H' shaped tube, as shown in the figure, Landolt introduced a solution of sodium chloride \[\ce{[NaCl]}\] and silver nitrate \[\ce{[AgNO3]}\] in the limbs of the tube and sealed it and weighed it.
- The solutions were mixed by shaking to obtain a white precipitate of silver chloride.
- The tube was again weighed after the experiment.
Result: Weight of H tube + reactants = Weight of H tube + products.
Hence, the total mass of reactants = total mass of products
