2.5 PH (vary from 2.3 to 4.0) Fresh tends to be more acidic than bottled.
Lemons Clearly have more acids in them because of the vfb
Lemon juice is more acidic, it has a pH level of 2.3. Very acidic substances are < 7.0 on the pH scale. Vinegar is about 2.9 on the pH scale.
A lemon because of it's lower pH.

a lemon is more sour than a grapefruit because it is more acidic.
Lemon Juice is more acidic.
Is a tomato acidic?
The answer is lemon is the most acidic with pH 2; the next most acidic is tomato with pH 4.The soap with pH 10 is alkaline; and ammonia with pH11.5 is more alkaline than the soap.To understand pH, always remember that the values from 1 to 7 are all acidic, neutral is 7.5, and all the values from 8 to 14 are alkaline.
Tomato is acidic.
I think Limes are
The pH scale is the negative base 10 logarithm of the hydrogen ion concentration. Thus, a pH of 2 means [H+]= 10-2 while a pH of 4 means [H+]= 10-4. Thus, lemon juice is 100 (102) times more acidic than tomato juice.
This is a huge mistake as most tomatoes are not acidic enough without added lemon juice. You should plan on refrigerating them and using soon.
definetely not watermelon. it is sweet. most likely it is lemon.
