A saturated solution of kcl is prepared at 25degree celsius. What would happen if temperature is cooled to 10degree celcius?
When a saturated solution of KCl is prepared at 25 degrees Celsius and then cooled down to 10 degrees Celsius, several things could happen.
Firstly, it's worth noting that temperature has an effect on the solubility of most substances. In general, the solubility of solid solutes in water tends to increase with increasing temperature.
However, in the case of KCl, its solubility in water decreases as the temperature decreases. This means that as the solution is cooled from 25 degrees Celsius to 10 degrees Celsius, less KCl will be able to remain dissolved in the water.
As a result, some of the KCl present in the solution will start to precipitate out as solid crystals. These crystals will be visible as solid particles in the solution. The amount of KCl that will precipitate depends on the difference between the initial concentration of the saturated solution at 25 degrees Celsius and the solubility of KCl at 10 degrees Celsius.
To further explore this, you can refer to a solubility table or graph that shows the solubility of KCl at different temperatures. By comparing the solubility of KCl at 25 degrees Celsius and 10 degrees Celsius, you can determine the extent of precipitation that may occur when the temperature is cooled.
