Answer

All very similar. I think it also depends on your taste.

Something is Sour or Tart because it usually contains a kind of ACID, therefore is ACIDIC.

Tart and Sour are different degrees of acidity/bitterness.

Tart is usually less acidic, sweet with a touch of sour (still delicious). Like some grapes, kiwi fruit or berries.

But sour can be too sour and not edible like a lemon or 醋.

Answer

Sour is a taste, acidic is one, which creates acid and acid is a dangerous substance or drug)))
