Green
blue-pinky colour.
Because tooth paste is a base because anything that turns a blue or green when mixed with red cabbage juice(indicator) is a base.
*shrugs* idk. if the lime stuff is clear then red but if the lime stuff is green then Santa Claus
I've never heard of it changing color when it is cooled, but it does change color with pH, and can be used as an indicator for acids and bases.See the Web Links for more information about using cabbage color as a pH indicator.
Pink or red
When sodium hydroxide is added to red cabbage juice, the cabbage juice will change color. The cabbage indicator will turn from red/pink to blue/purple because sodium hydroxide is a strong base, causing a shift in the pH of the solution. This color change is due to the anthocyanin molecules in the red cabbage juice reacting with the change in acidity.
Adding iodine to sodium hydroxide will result in brown color due to the formation of sodium iodide and sodium hypoiodite.
none, it is clear
Sodium hydroxide does not produce a distinct color in a flame test. It is the sodium ions that give a bright, persistent yellow color to the flame.
When copper sulfate is added to sodium hydroxide, a blue precipitate of copper hydroxide is formed. The color change observed is from the initial blue color of copper sulfate to the blue precipitate of copper hydroxide.
NOTHING! Sodium hydroxide (NaOH) is a base, and BLP does not change color with a base.
color less (white)
Phenolphthalein turns pink in basic solutions
A reaction occur and sodium acetate is formed.
its kind of orange and i think the ph of NaOH is 8-10................... double check though coz i tested this with red cabbage juice so i am not sure.................. \\\
Sodium hydroxide is a strong base, so it will turn blue litmus paper to red. This color change is due to the alkaline nature of sodium hydroxide which reacts with the blue litmus paper to change its color.
Hydrochloric acid: yellow color Sodium hydroxide: brown color Sugar: unchanged
