Universal indicator would likely turn red in ethanol, indicating that it is acidic.
Universal indicator changes color in different pH ranges. In the case of ethanol, which is pH-neutral, universal indicator would likely show a green color.
Citric acid is a weak acid, so it would turn a universal indicator to orange or red.
Universal indicator would turn blue or purple in soil containing alkaline.
Orange juice would be acidic in nature, so it would likely turn red or pink in Universal indicator due to its low pH level.
A weak acid would typically be a shade of orange or red in universal indicator, indicating a pH of around 4-6.

Universal indicator would turn blue or purple in soil containing alkaline.
Universal indicator would turn dark blue or purple in caustic soda, indicating a high pH level.
The Universal Indicator would go green which is pH 7.
Ammonia gas would turn universal indicator paper blue or purple depending on the concentration of ammonia present.
Orange juice would be acidic in nature, so it would likely turn red or pink in Universal indicator due to its low pH level.
A weak acid would typically be a shade of orange or red in universal indicator, indicating a pH of around 4-6.
A weak alkali would typically turn blue or purple in Universal Indicator, indicating a pH around 8-10.
Because Coffee is a dark colour and if your testing it with universal indicator paper the paper might stain from the strong coffee colour and not be entirely accurate. I have never tried this personally its just as assumption.
