which of these has the highest h⁺ concentration?\nmultiple choice\nlemon juice, ph = 2.3\nred wine, ph = 3.2\ntomato juice, ph = 4.7\nsaliva, ph = 6.6\nhousehold ammonia, ph = 10.8
Answer
Explanation:
Step1: Recall pH - $H^+$ relationship
The formula for pH is $pH = -\log[H^+]$, so $[H^+]=10^{-pH}$. Lower pH means higher $H^+$ concentration.
Step2: Compare pH values
We have lemon juice (pH = 2.3), red wine (pH = 3.2), tomato juice (pH = 4.7), saliva (pH = 6.6), household ammonia (pH = 10.8). The lowest pH is 2.3.
Answer:
Lemon juice, pH = 2.3
