SWEET FACT

Adding salt to pineapple will make it taste sweeter

When the common salt (NaCl) dissolves into the pineapple it will break apart into sodium(Na) and chloride(Cl) ions.

The sodium ion will then react with the malic and citric acids present in the pineapple to form neutral sodium salts.

Acids normally have a sour taste but when they are converted into neutral compounds they lose this sourness, and so the pineapple tastes sweeter.
