Answer:
The correct statements are:
1. Table salt is soluble in water, table salt (NaCl) get dissociate in water as NaCl = Na+ + Cl-.
2. Zinc sulfate is also soluble in water, as zinc sulfate gets dissociate in water as ZnSO4 = Zn2+ + SO42-.
3. The solubility of carbon dioxide gas in water increases with partial pressure and drops down with the drop in partial pressure.
The incorrect statements are:
1. Gases do not get easily soluble in water at high temperatures. The higher kinetic energy makes more motion in the molecules of gas which dissociate intermolecular bonds and escape from solution.
2. Ethanol and hexane are not miscible, as ethanol is hydrophilic due to the presence of -Oh group and hexane is hydrophobic. So, these compounds will not mix.
