What Color will turn a solution of washing soda and lemon juice when its neutralized?
When a solution of washing soda (sodium carbonate) and lemon juice (which contains citric acid) is neutralized, the resulting solution typically turns from a basic (alkaline) state to neutral, which may not produce a distinct color change. However, if a pH indicator like phenolphthalein is used, the solution will shift from pink (indicating basicity) to colorless as it approaches neutral pH. If using universal pH indicator, the color may change to green, indicating a neutral pH around 7.
What else can I help you with?
A procedural change would be required if a student wanted to determine the acidity of tomato juice by titrating a juice sample with NaOH solution Briefly explain?
A procedural change would be required so that the student includes an indicator, like phenolphthalein, in the tomato juice sample, which changes color at the endpoint of the titration. This indicator helps visually identify when all the acid in the tomato juice has been neutralized by the NaOH solution, ensuring accurate determination of the juice's acidity.
What color you get after mixing lemon juice to BTB solution?
When you mix lemon juice with bromothymol blue (BTB) solution, the color will change from blue to yellow. This is because the acidity of the lemon juice causes the BTB indicator to shift to its yellow color.
What color change does bougainvillea juice undergo when mixed with dove solution?
Bougainvillea juice will turn from its original color to pink when mixed with dove solution, due to the presence of anthocyanin pigments in the bougainvillea juice reacting with the alkaline nature of the dove solution.
What color is the solution of red cabbage and lemon juice when first mixed?
The color remain red because vinegar is an acidic solution.
When blueberry juice is mixed with a solution of baking soda it turns what color?
grey
What color does red cabbage juice change depending on the pH?
Cabbage contain Anthocyanins called Cyanidin. These are responsible for changing color with pH. Changing the pH affects the shape of the molecule which, in turn, changes its wavelength absorption.
What color does washing soda turn when mixed with red cabbage juice?
it goes red i think not sure but i think
What are some Examples of solubility?
washing up liquid, Orange Juice, Grape Juice
What will be the color of red cabbage extract in lemon juice?
Red in acidic solution
How do you get back the color of turmeric after the reaction of turmeric and calcium hydroxide solution?
add lemon juice
Is phenolphthalein in cabbage juice?
Phenolphthalein is not naturally present in cabbage juice; however, cabbage juice can serve as a pH indicator due to the presence of anthocyanins, which change color based on acidity or alkalinity. When cabbage juice is mixed with a basic solution, it will typically turn a greenish-yellow color, while in acidic solutions, it may appear reddish-purple. If phenolphthalein is added to cabbage juice, it could alter the color response based on the pH level of the solution.
What color does cabbage juice turn in a base?
Cabbage juice changes color in a basic solution, turning from purple to green or blue. This is due to the pH indicator properties of anthocyanins in the cabbage, which shift in color depending on the acidity or basicity of the solution. In more alkaline environments, the pigments reflect different wavelengths of light, resulting in the color change.
