Question

archit dropped a crystal of copper sulphate into two beakers A and B containing hot water and cold water respectively. After keeping them beakers undisturbed for sometime, what did he observe and why❓​

Answer 1

any salt dissolve more in hot solvent. color of beaker A is less dark than the B. beaker B may have some undissolved residue.

hot water has more interarticular space due to more kinetic energy. thus it dissolve more in beaker B. hope you understood.
