yes i drank it once and i ended up in hospital for 3 weeks as universal indicator contains a poisonous chemical called methanol which is very harmful to the human body as well as any other animals. i now have partial blindness and it caused damage to the insides of my body. i have now realised that it was a very bad thing to do and no one should ever ever EVER drink chemicals from a lab. please take this into consideration when you perform an experiment as i would hate for somones else to have to go through this traumatic ordeal i have experienced.
Universal indicator is just that - an indicator. It is not intended as an accurate measurement system.
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.
A neutral solution will turn universal indicator green.
The Universal Indicator would go green which is pH 7.
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.
Put in some universal indicator and find the colour. Correspond this to bthe pH scale to find how dangerous it is.
The universal Indicator was invented in 1923 by Yamada
Universal Indicator Green was created in 1995.
Universal Indicator Yellow was created in 1993.
Universal Indicator Blue was created in 1992.
Universal Indicator Red was created in 1993.
Universal indicator is just that - an indicator. It is not intended as an accurate measurement system.
Alkalis turn universal indicator blue or purple.
Green is the color that universal indicator turns to when it is neutral.
The universal indicator turns red in acidic solutions.

pH of ammonia is around 11-12. Hence when you put it in a universal indicator, you get purple color.
