a student is trying to determine if a solution is acidic or basic. she does not have any litmus paper. which would she most likely use to get a reading on her solution?\nvinegar\nsoap\ncabbage juice\naquarium water
Answer
Brief Explanations:
Cabbage juice is a natural pH - indicator. It changes color depending on whether the solution is acidic or basic. Vinegar is acidic itself and won't help test other solutions. Soap is basic and also not a testing agent. Aquarium water has no special property to test acidity or basicity of other solutions.
