Question

ph of lemon and tomatoes​

Answer 1

Answer:

This solution is weakly basic. Remember, a pH of 7.0 is neutral. Anything above that (7–14) is basic, and anything below that (0–6) is acidic. The pH of lemon juice is about 2.0, whereas tomato juice's pH is about 4.0.

Answer 2

Although tomatoes usually are considered an acid foods, some are now known to have pH values slightly above 4.6. Therefore, if they are to be canned as acid foods, tomato products must be acidified to a pH of 4.6 or lower with lemon juice or citric acid
