Chemistry
Distinguish between a common acid base indicator and a universal indicator.
Answer
Difference between a common acid base indicator and a universal indicator:
| Common acid-base indicator | Universal indicator |
|---|---|
| Common acid-base indicators test whether a solution is acidic, basic or neutral. | Universal indicator gives a spectrum of colours depending upon how acidic or alkaline a solution is. |
| Common acid-base indicators does not give the exact pH value of the solution. | Universal indicator helps to get a reasonably accurate pH value. |
