Because universal shows how strong or weak a substance is. Litmus just shows if its Alkaline or Acid.

What is the difference between an indicator and a universal indicator?
A pH meter uses a probe and voltmeter to measure pH digitally. Universal indicator is a mix of indicators that change colour to indicate the pH of the solution. pH meters are accurate and will detect changes quickly, whereas universal indicator is slow to change colour to indicate pH change.
How are universal indicators useful to scientist?
An Universal Indictator is more helpful because it shows the exact amount of acidity. Other indictators (example the red and blue litmus) just indicates whether or not the solution is acidic. The universal indicator gives you a specific color to which you can match a pH number therefore, telling you how acidic the soultion is.
Why methyl orange is used in titration of weak base against weak acid?
It is the best indicator for the situation. For other combinations of acids and bases other indicators are suited better. mostly it is because of how easy their colour changes or how obvious they are.
What characteristics limit the usefulness of indicators?
Chemical indicators measure the pH directly Chemical indicators are highly expensive They must be chosen for a specific pH range Chemical indicators cannot determine the exact value of pH of the solution
Why do indicators change colors?
indicators change colour because of your pee.
Is universal indicator always the best indicator?
No, not always. Some indicators are better suited for certain ranges; UI will provide a rough indication across a huge range, but other indicators can be more accurate across a small range, and this is when they are used.

What happens to all acids when an indicator is added?
universal indicator goes from yellow to dark red when put in an acid. there are many other indicators that all go different colours
Can you use indicator's for your car in GTA iv?
but other cars uses the indicators how? but why we cant use the indicators

What are the main 3 indicators?
litmus paper and pH scale i am not sure about the rest :)
Is a indicator an acid or base?
Yes, indicators are one or the other of those things.
Is an indicator base or acid?
Yes, indicators are one or the other of those things.
What does red cabbage indicator do that other indicators don't?
Nothing, but red cabbage is a simple pH indicator at home (red in acidic solutions).
Is vanilla an olfactory indicator?
clove oil is. in bases its characteristis smell cannot be detected.
