How will you prepare saturated solution of pottassium nitrate at 30 degrees Celsius
Dear Student,
A saturated solution is a solution in which no more solute can be dissolve at given temperature. The addition of any more solute will result in the accumulation of that solute in the bottom of the container.
To prepare the saturated solution of KNO3 at 30°C, take a measured volume of water (say 100 ml.) in beaker and warm it up to 30°C. Then add KNO3 pinch by pinch at constant stirring and observe the point when no more KNO3 is dissolving in water. At that point the added pinch of KNO3 will appear at the bottom of beaker and your saturated solution is prepared.
On cooling, crystals(particles) of KNO3 separate from the solution. This is a separation technique is known as crystallisation.
