Answer:
Since the drinks are edible, Dorji can taste the drinks to make the decision.
If the drink tastes sour, it is acidic in nature.
If the drink tastes bitter, it is basic in nature.
If the drink has no taste, it is neutral in nature.
→ If Dorji has a litmus indicator(solution or paper), he can test with it.
→ He should pour a drop of the drink on the paper.
→ In case he has a blue litmus paper and the colour changes to red, drink is acidic.
