the chart shows the solubility of different substances. which statement is represented by the graph? temperature can change the solubility of a solute. temperature has no affect on the solubility of a solute. salt has a greater solubility than sugar. nitrite salt has a greater solubility than sugar. solute temperature g/100 g water sugar 20°c 204 sugar 100°c 487 salt 20°c 36 salt 100°c 39 nitrite salt 20°c 81 nitrite salt 100°c 160
Answer
Explanation:
Step1: Analyze sugar solubility
For sugar, at 20°C solubility is 204 g/100 g water and at 100°C it is 487 g/100 g water. Solubility increases with temperature.
Step2: Analyze salt solubility
For salt, at 20°C solubility is 36 g/100 g water and at 100°C it is 39 g/100 g water. Solubility slightly increases with temperature.
Step3: Analyze nitrite - salt solubility
For nitrite - salt, at 20°C solubility is 81 g/100 g water and at 100°C it is 160 g/100 g water. Solubility increases with temperature.
Step4: Compare solubilities
At both 20°C and 100°C, sugar has higher solubility than salt and nitrite - salt. Also, solubility of all three substances changes with temperature.
Answer:
Temperature can change the solubility of a solute.
