Universal indicator paper will turn blue or blue-green when dipped into ammonia solution, indicating that the solution is basic or alkaline.
Ammonia typically appears blue on a universal indicator.
Ammonia is a base, and will turn red litmus blue.
Ammonia solution is typically colorless, although it may appear slightly yellowish due to impurities.
A neutral solution added to universal indicator will turn green.
Yellow
Universal indicator turns blue or purple in ammonia solution. Ammonia is a weak base, so it causes the indicator to change to a blue or purple color on the pH scale. This color change indicates the basic nature of the solution due to the presence of ammonia molecules.
Universal indicator paper will turn blue or blue-green when dipped into ammonia solution, indicating that the solution is basic or alkaline.
Ammonia typically appears blue on a universal indicator.
The phenolphthalein indicator is pink in basic solutions.
Ammonia gas would turn universal indicator paper blue or purple depending on the concentration of ammonia present.
yellow
Ammonia is a base, and will turn red litmus blue.
Ammonia solution is typically colorless, although it may appear slightly yellowish due to impurities.
A neutral solution added to universal indicator will turn green.
The universe as a whole does not have a specific colour. However, in a science experiment, when an antacid solution is added to a universal indicator, it may change colour based on the pH level of the solution. This change in colour signifies the acidity or alkalinity of the solution.
The color of universal indicator solution in a neutral solution is green.
