It is a substance used to determine the strengths of acids and alkali.
It changes color according to the pH of the material its in. It is so useful because the color also tells you how strong the substance is. As an example, if you were to put a few drops of the indicator in water it would go green. A few drops of it in cleaning products and it would go a deep purple.
A universal indicator can give various colors to a huge variety of pH ranges.

Universal indicator is a pH indicator solution used to determine the pH of a substance. It contains a mixture of different indicator dyes that change color depending on the pH level of the solution being tested. This allows for a broad range of pH values to be identified by observing the color change.

Why does universal indicator not always give an accurate result?
Universal indicator is just that - an indicator. It is not intended as an accurate measurement system.
Why is water used as the universal indicator?
Water is NOT Universal Indicator. Water is often referred to as a Universal Solvent as a large number of substances are soluble in it. Universal Indicator is a chemical agent that can be used to test the pH of a liquid.
What color do neutral solution turn the unniversal indicator?
A neutral solution will turn universal indicator green.
What is the colour of universal indicator solution in a neutral solution?
The color of universal indicator solution in a neutral solution is green.
What substance will make universal indicator turn orange?
An acidic substance will turn universal indicator orange. This occurs because universal indicator contains a mixture of dyes that change color based on the pH of the solution. In an acidic environment, the indicator will shift towards the orange end of the color spectrum.

What is the colour of the universal indicator in the acid?
The universal indicator turns red in acidic solutions.
What colour universal indicator turns to a neutral?
Green is the color that universal indicator turns to when it is neutral.
What coulor do alkalis turn universal indicator?
Alkalis turn universal indicator blue or purple.
Why is water used as the universal indicator?

What is the colour of ammonia on a universal indicator?
Ammonia typically appears blue on a universal indicator.
What effect does and alkali have on an universal indicator?
When an alkali is added to universal indicator, the color of the indicator will typically change to blue or purple, indicating a high pH. Alkalis are substances that have a pH above 7 and tend to turn universal indicator towards the blue end of the spectrum.
