Expert Answer

Step 1

Table 9.1 (data)

Appearance

KNO3+water before heating

White solid + water (Insoluble)

NaCl + water before heating

White solid + water (Insoluble)

KNO3+ water after heating

Clear solution (completely soluble)

NaCl + water after heating

White solid + water (Insoluble)

KNO3+ water after cooling

White solid + water (Insoluble)

NaCl + water after cooling

White solid + water (Insoluble)

Table 9.2 (report)

 

Solute with solubility most influenced by temperature

KNO3

 

 

Reason for choice

Increase in temperature increases kinetic energy of ions of potassium, nitrate, and water molecules, which leads to movement...
