Multiple Choice

Why does sodium bromide (NaBr) readily dissolve in water?

Because bromide ions form insoluble compounds with sodium.

Because water cannot break the ionic bonds in sodium bromide.

Because sodium bromide is a covalent compound that reacts with water.

Because all sodium salts are soluble in water according to solubility rules.

Verified step by step guidance

Step 1: Understand the nature of sodium bromide (NaBr). It is an ionic compound composed of sodium ions (Na\^+) and bromide ions (Br\^-).

Step 2: Recall that water is a polar solvent, meaning it has partial positive and negative charges that can interact with ions.

Step 3: Recognize that when NaBr is placed in water, the polar water molecules surround the Na\^+ and Br\^- ions, a process called hydration or solvation.

Step 4: Apply the solubility rules, which state that all sodium salts are soluble in water, meaning NaBr will dissociate completely into its ions in aqueous solution.

Step 5: Conclude that NaBr dissolves readily in water because the ionic bonds are overcome by the strong ion-dipole interactions between the ions and water molecules, leading to dissolution.
