Final answer:
When sodium sulfate is added to dichloromethane, no chemical reaction occurs. Sodium sulfate is an ionic compound and dichloromethane is a nonpolar solvent, so they do not chemically react with each other. However, sodium sulfate is not soluble in dichloromethane.
Step-by-step explanation:
When sodium sulfate is added to dichloromethane, no chemical reaction occurs. Sodium sulfate is an ionic compound and dichloromethane is a nonpolar solvent, so they do not chemically react with each other. However, it is important to note that sodium sulfate is soluble in water but not in dichloromethane, so if sodium sulfate is added to dichloromethane, it will not dissolve.
