- 6-18 Suppose you prepare a solution by dissolving glucose in water. Which is the solvent, and which is the solute?arrow_forward6-22 Answer true or false. (a) Water is a good solvent for ionic compounds because water is a polar liquid. (b) Small covalent compounds dissolve in water if they can form hydrogen bonds with water molecules. (c) The solubility of ionic compounds in water generally increases as temperature increases. (d) The solubility of gases in liquids generally increases as temperature increases. (e) Pressure has little effect on the solubility of liquids in liquids. (f) Pressure has a major effect on the solubility of gases in liquids. (g) In general, the greater the pressure of a gas over water, the greater the solubility of the gas in water.
