Ramesh took two beakers A and B containing hot water and cold water respectively . In each beaker he dropped a crystal of copper sulphate . He kept it undisturbed. After some time what did he observe ? Why ?
Answered by DrBob222
CuSO4.5H2O is soluble in water. With time the CuSO4 dissolves and begins to diffuse throughout the beaker. Left undisturbed, even after a long time, the bottom of the beaker will be quite blue and the upper portions will be much less blue in color.
