I have just done an experiment, and found out that lime juice is more acidic than oranges and oranges are more acidic than watermelons.. What is the cause of this? Please don't just say because lime juice is more sour. Scientific answer plz!

Although fruits get sweeter as they ripen, as starches change to sugars, some fruits are just more sour than others genetically. Citrus fruits contain citric acid. Lemons and limes contain more than oranges and tangerines . All fruits contain different types of acids. Grapes have tartaric. Apples have acetic and malic. Some of the acids turn to ketones and esters as the fruit ripens. It is the special combination of the organic acids and alcohols that gives the fruits their characteristic odors.(esters)

This is because fruits contain different amounts and types of acids. For example in limon there is citric acid and vitamin C which is also acidic. I guess there are many more organic acids but those two are the main.
In orange there is obviously less acid and in watermelon even less...

some fruits contain different concentrations of the same acid thus causing different acidity. In other cases the strength of the acid in fruit may be different from the strength of acid in another even if they are in same concentration. They have to be different acids though of course.

Because fruits have different acidity as measured by pH contents.

check the PH reading
