C
NaCl
D
AgCl
Verified step by step guidance1
Step 1: Understand the principle 'like dissolves like,' which means polar solvents (like water) dissolve polar or ionic substances well, while nonpolar solvents dissolve nonpolar substances.
Step 2: Identify the nature of each substance: CCl_4 is nonpolar, PbSO_4 is an ionic compound but sparingly soluble, NaCl is an ionic compound and highly soluble in water, and AgCl is ionic but has very low solubility in water.
Step 3: Recognize that water is a polar solvent and tends to dissolve ionic compounds that dissociate easily into ions, such as NaCl.
Step 4: Compare solubility: NaCl dissociates readily in water, making it highly soluble, whereas PbSO_4 and AgCl have low solubility due to their lattice energies and low dissociation.
Step 5: Conclude that NaCl is most likely to dissolve easily in water because it is an ionic compound with high solubility in polar solvents like water.
