why universal indicator is called universal indicator?
Salt water typically forms a neutral pH solution, so it will likely appear green in universal indicator.

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.
Salt water typically forms a neutral pH solution, so it will likely appear green in universal indicator.
Bleach is a basic solution, so it will turn universal indicator to a purple color. This indicates a high pH level in the bleach solution.
Universal indicator is just that - an indicator. It is not intended as an accurate measurement system.
