The universal Indicator was invented in 1923 by Yamada
The alkali makes a universal indicator turn blue.

A universal indicator changes color in response to the pH of a liquid. Do determine the pH of the liquid, you need to refer to a color chart that tells you which color indicates which pH.
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.

The universal indicator was developed by Arnold J. Olsen in 1933. It is a mixture of several different indicators that change color over a wide range of pH levels.
Universal Indicator Red was created in 1993.
Universal Indicator Blue was created in 1992.
Universal Indicator Green was created in 1995.
Universal Indicator Yellow was created in 1993.
Universal indicator is just that - an indicator. It is not intended as an accurate measurement system.
The universal indicator turns red in acidic solutions.
Green is the color that universal indicator turns to when it is neutral.
Alkalis turn universal indicator blue or purple.
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.
pH of ammonia is around 11-12. Hence when you put it in a universal indicator, you get purple color.
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.
