What is the advantage of olfactory indicator over normal indicator |
|
Answer» Advantage of olfactory indicators over universal indicators is that olfactory indicators also helps us to guess the substance with their smell that whether it is acidic or basic.... but this property is not shared by universal indicated.... as they help us to judge only with change in color and not with smell The advantage of the universal indicator is that it displays a variety of colors over the whole pH scale. This makes it possible to determine an approximate pH of a solution over a range from 1-14. whereas, A commonly used acid-base indicator is litmus. |
