Manya is blindfolded. She is given two unknown solutions to test and determine Class 7
Manya is blindfolded. She is given two unknown solutions to test and determine whether they are acidic or basic. Which indicator should Manya use to test the solutions and why? Class 7
Answer:
She should use an olfactory indicator to test the solutions. Olfactory indicators change their smell in acidic or basic solutions. For example, substances like onion produce a strong smell in an acidic solution and a mild smell in a basic solution.
