which solution has the greatest number of hydroxide ions?\n baking soda, ph = 9\n milk, ph = 6\n tomato juice, ph = 3.5\n vinegar, ph = 2

which solution has the greatest number of hydroxide ions?\n baking soda, ph = 9\n milk, ph = 6\n tomato juice, ph = 3.5\n vinegar, ph = 2

Answer

Explanation:

Step1: Recall pH - OH⁻ relationship

The higher the pH value, the greater the concentration of hydroxide ions ($\text{OH}^-$).

Step2: Compare given pH values

We have baking soda with pH = 9, milk with pH = 6, tomato juice with pH = 3.5 and vinegar with pH = 2. Among these, baking soda has the highest pH value.

Answer:

baking soda, pH = 9
