Respuesta :
The correct answer is letter C. the temperature of the solution. In a typical solubility curve, the relationship is between temperature of the solutions against the grams of the solute per 100 grams of water. As the temperature increases, the solute also increases and its solubility.
The correct option is C.
Solubility curve refers to the graphical representation of the variations that exist between the temperature of a solution and the solubility of the solute. The graph has two axes, the Y axis and the X axis. The X axis display the temperature of the solution while the Y axis display the solubility of the solute with the unit of gram of salt in 100g of the solvent. As the temperature increases, the solubility of the solute also increases.
