Solution

Dear Student,

In order to check for an acidic cold drink Sita should use three blue litmus paper.
She should dip a blue litmus paper inside each cold drink bottle.
The one cold drink in which the blue litmus turn red will be an acidic cold drink.
This is due to the fact that an acid solution turns blue litmus red. A basic solution turns red litmus blue and a neutral solution shows no colour change with litmus paper.

Regards
