which solution has the greatest number of hydroxide ions?\nbaking soda, ph = 9\nmilk, ph = 6\ntomato juice, ph = 3.5\nvinegar, ph = 2
Answer
Explanation:
Step1: Recall pH - OH⁻ relationship
The higher the pH, the lower the hydrogen - ion ($H^+$) concentration and the higher the hydroxide - ion ($OH^-$) concentration.
Step2: Compare pH values
We have baking soda (pH = 9), milk (pH = 6), tomato juice (pH = 3.5), and vinegar (pH = 2). Baking soda has the highest pH among them.
Answer:
baking soda, pH = 9
