Answer 2

Answer:

Usually the ph value of our mouth ranges from 6.5 to 7. But when we take lime juice it brings down the ph value owing to the presence of the citric acid in it. Now ptyalin is nothing but an enzyme that helps in better digestion but as ph lowers, it may be difficult to digest the food and problems may increase for you.
