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
