Answer: Increasing the temperature of of the solution increases the solubility of the solute
Explanation:
In the graph , two of axes represents amount of solute and temperature of the solution. from the graph we can observe that on increasing the temperature of the solution, more and more amount solute is getting dissolved in a solution. Which directs us to towards a conclusion from the given graph which is increasing the temperature of the solution increases the solubility of the solute.
Solubility of KCl and NaCl is slightly increasing with increase in temperature where as solubility of [tex]KNO_3[/tex] is sharply increasing on increasing the temperature of the solution.
Hence, the correct option is (C).
