Ravi added a small amount of common salt to water taken in a graduated cylinder. On dissolution,there was no detectable change in the level of water. Explain why this is so.
(N/A) When we dissolve salt in water,the volume of water remains the same because the particles of salt occupy the spaces between the particles of water and thus become invisible.
This observation demonstrates that particles of matter have spaces between them.
