NaCl is commonly known as what compound?

NaCl is sodium chloride, formed when sodium ions pair with chloride ions in a 1:1 ratio to create a stable ionic compound. The naming convention for simple salts uses the metal name followed by the nonmetal with an -ide ending, so this compound is called sodium chloride. It’s commonly known as table salt, used worldwide for flavoring and food preservation. The other options would correspond to different ions—nitrate, fluoride, or hydroxide—giving NaNO3, NaF, or NaOH with distinct properties and uses.
