Question
Whena saturate solution of LiCl was chilled someof the solid solute formed
LiCl (s)---- Li + (aq) + Cl - (aq)
a) The stress placed on the system was ( an increase/ a decrease) intemperature
b) The system response wasan attempt to ( increase / decrease) the temperature
c) As a result the equilibrium shifted to the ( right / left) and the solubility of LiCl ( increase / decrease )
d) At the lower temperature the solution of LiCl was
1) unsaturated 2) Saturated 3) Supersaturated 4) Not enought information given
Explain please!
Explanation / Answer
a) The stress placed on the system was a decrease in temperature.
b) The system response was an attempt to decrease the temperature.
c) As a result the equilibrium shifted to the left and the solubility of LiCl decrease.
d) At the lower temperature the solution of LiCl was Supersaturated
Unsaturated solution : the solution in a position to dissolve some more amount of solute in it.
Saturated solution : in a solution very small amount of solute is un dissolved.No more amount of solute is not dissolved further.
Super saturated solution : Supersaturation is a state of a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances.if temperature decreases some amount of material will precipitate.
