    Answer: -

    Baking soda having a pH of 9, has the maximum number of hydroxide ions.

    Explanation: -

    More the pH of a solution, the more basic it is and more the number of hydroxide ions it has.

    From the question we find that

    baking soda has a pH = 9

    milk has a pH = 6

    tomato juice has a pH = 3.5

    vinegar has a pH = 2

    Thus among them baking soda has the highest pH.

    So baking soda is the most basic and has the maximum number of hydroxide ions.
