    The attraction of Br⁻ to H⁺ and Na⁺ to OH⁻

    Explanation:

    NaBr is an ionic compound and would easily be dissociated by water in solutions.

    Water is a polar covalent molecule and with a partial dipole on it. The hydrogen ions have a positive charge and the hydroxyl ions are negatively charged.

    In solutions with water, NaBr dissolves. This releases the sodium and bromide ion into the solution. The Bromide ion becomes hydrated and surrounded by the water molecules. The negatively charged end of the water molecule bonds with the Na ion and the positive end bonds with the negative part of the water molecule. This bonding provides the NaBr an ease of movement in its lattice structure.

    This procedure leads to the solubility of NaBr in water.
