Verified step by step guidance

Step 1: Understand that solubility rules help predict whether a compound is soluble or insoluble in water. Compounds that are highly soluble tend to dissolve faster because more ions separate into solution quickly.

Step 2: Recognize that PbSO4, CaCO3, and AgCl are generally considered sparingly soluble or insoluble salts, meaning they have low solubility in water at room temperature.

Step 3: Recall that NaCl is a soluble salt because all common sodium salts are soluble in water, which means NaCl dissociates readily into Na⁺ and Cl⁻ ions.

Step 4: Since NaCl is highly soluble, it will dissolve faster in water compared to PbSO4, CaCO3, and AgCl, which have limited solubility and dissolve more slowly.

Step 5: Therefore, by applying solubility rules and understanding ionic dissociation, you can conclude that NaCl dissolves faster in water at room temperature than the other listed compounds.
