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.
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.
Does it turn to universal indicator blue?
The universal indicator turns blue in the presence of alkaline (basic) substances, typically with a pH greater than 7. If a solution is acidic (pH less than 7), the indicator will show colors ranging from red to yellow. Therefore, whether the indicator turns blue depends on the pH level of the solution being tested.
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 Universal Indicator would go green which is pH 7.
What substances turn universal indicator red?
all acidic substances with a PH below 7< turn the Universal indicator red due to their acidity.
Why is water used as the 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.
Is universal indicator paper the same as blue litmus paper?
No totally different, universal indicator is a mixture of chemical which shows the precise p.H of a substance, blue litmus paper reveals whether the substance is acidic or alkaline.
When was universal indicator invented?

When was Universal Indicator Blue created?
Universal Indicator Blue was created in 1992.
When was Universal Indicator Red created?
Universal Indicator Red was created in 1993.
Will strong acids turn universal indicator paper purple?
The pH scale ranges from 0-14. Universal indicator makes very acidic substances (with a pH of around 0) appear dark red, neutral ones green and very alkaline ones dark blue.
