Multiple Choice

According to solubility rules, why does NaBr readily dissolve in water?

NaBr is a covalent compound and covalent compounds are generally soluble.

All sodium salts are soluble in water.

Bromide ions always form insoluble compounds.

Water reacts with NaBr to form a precipitate.

Verified step by step guidance

Recall the general solubility rules for ionic compounds in water, which state that most sodium (Na\textsuperscript{+}) salts are soluble.

Recognize that NaBr is an ionic compound composed of Na\textsuperscript{+} (sodium ion) and Br\textsuperscript{-} (bromide ion).

Understand that water is a polar solvent and dissolves ionic compounds by surrounding and stabilizing the individual ions through ion-dipole interactions.

Note that bromide ions (Br\textsuperscript{-}) generally form soluble compounds except with a few exceptions (like AgBr), but NaBr is not one of those exceptions.

Conclude that NaBr readily dissolves in water because all sodium salts are soluble, and water effectively separates and stabilizes the Na\textsuperscript{+} and Br\textsuperscript{-} ions.
