Chemistry 9th Edition

a. The polar solute will dissolve in water. The nonpolar solute will not dissolve in water. b. KF is dissolved and splits into its ions. $C_6H_{12}O_6$ dissolves but remains intact in solution. c. $RbCl$ will dissolve in water and split into its ions. $AgCl$ will not dissolve in water. d. $HNO_3$ will dissolve and split into its ions. $CO$ will dissolve but will remain intact.
a. Water is polar substance and only dissolved polar substances as like dissolves like. Therefore, a polar substance will dissolve while a nonpolar substance will not dissolve. b. KF is an ionic compound and therefore will dissociate into its ions. $C_6H_{12}O_6$ is a covalent compound and therefore remains intact when dissolved in water. c. Consult solubility chart. d. $HNO_3$ is an ionic compound and therefore will dissolve and split into ions. $CO$ is a covalent compound and therefore remain intact in solution.
