Answer:- Cola-flavored soda:2.6, cranberry juice:2.9 and pickle juice:5.5 are acidic.
Explanations:- As per the pH scale, the solution is acidic if the pH is below 7 and the solution is basic if the pH is above 7. The solution is neutral if the pH is exactly 7.
There are only three solutions with pH value below 7 and so they are acidic. these three solutions are, cola-flavored soda, cranberry juice and pickle juice.
Rest of them are basic as their pH value is greater than 7.
