What chemical change allowed vinegar to change a mustard mix with ammonia base to change back to its original color?
It returned the mustard back to its original acidic state. Mustard contains a natural pH indicator that is yellow when it is acidic and brownish when it is neutral or basic.
Why does ammonia change color if it cleans a penny?
When ammonia cleans a penny, it reacts with the copper oxide layer on the penny's surface. This reaction removes the oxide layer and exposes the shiny copper underneath, causing the penny to appear brighter or even change color.
Why can ammonia change a flower's color through a flower's pigment?
Ammonia increases the pH of the solution around the flower, which can alter the structure of the pigment molecules in the flower petals. This change in structure can affect the way the pigment molecules interact with light, leading to a shift in the flower's color.
What colour would ammonia turn if universal indicator is added?
The pH of the base ammonia is, depending on its concentration between 11.1 (0.1M) and 12.1 (10M) so the color of the most common Yamada's Universal Indicator will be purple (or blue if pH < 11, ready to use household ammonia)
What is the colour change before and after Aqueous ammonia is added to a test tube containing a precipitate of copper II hydroxide and the precipitate dissolves?
The precipitate of copper II hydroxide is initially blue-green. When aqueous ammonia is added, the precipitate dissolves to form a deep blue solution due to the formation of a complex ion called tetraamminecopper (II) complex.
What color change is seen when ammonia is added to mustard?
The yellow color in mustard comes from the rootstock of a plant called tumeric.

What color does ammonia turn when phenolphthalein is added?
Ammonia will turn pink when phenolphthalein is added, indicating that the solution is basic.
What is the colour of blue litmus paper in ammonia?
The color of blue litmus in ammonia will remain to be blue . However the color of red litmus will change into blue. This is because of the basic nature of ammonia.
Why does ammonia change color if it cleans a penny?
When ammonia cleans a penny, it reacts with the copper oxide layer on the penny's surface. This reaction removes the oxide layer and exposes the shiny copper underneath, causing the penny to appear brighter or even change color.
If Phenolphthalein solution is added to an ammonia-based solution of a window cleaner what color would it be?
It would turn pink. Phenolphthalein is an acid-base indicator that turns pink in the presence of a base like ammonia.

What color does gold and green make?
A mustard color
What is the color of marigold flower indicator when acidic substance is added to it?
When an acidic substance is added to marigold flower indicator, the color generally turns red or pink. This color change indicates the presence of acidity in the substance being tested.
Why doesn't dry litmus paper change color when added to dry ammonia gas?
Dry litmus paper does not change color when added to dry ammonia gas because ammonia gas is not acidic or basic enough to react with the litmus paper. Litmus paper changes color in the presence of acids (turns red) or bases (turns blue), but ammonia gas is a weak base and does not exhibit a strong enough reaction to cause a color change.
What color does ammonia change when mixed with cabbage juice?
Basic colour of C.J. is purple blue
What happens when you added Ammonia to copper sulfate?
When ammonia is added to copper sulfate, a blue precipitate of copper hydroxide forms, as they react to produce a complex ion. The reaction can be represented by the equation: CuSO4 + 4NH3 -> [Cu(NH3)4]SO4.
