actually yes your hair color will eventually change in lemon juice although it does make your hair dry and brittle..:)
When lemon juice is mixed with vinegar, it does not change color significantly. Lemon juice is already acidic and adding vinegar, which is also acidic, will not produce a significant color change.
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.
because the juice of the lemon is sour and that's the normal colour of sour:yellow.
This color change occurs due to a chemical reaction between the ginger's compounds (anthocyanins) and the acidic lemon juice. The anthocyanins in the ginger react with the acid to change color, resulting in the pinkish hue.
It's possible that the asparagus juice contains an indicator chemical which is reacting to the acid in the lemon juice. (Note that I don't know exactly which indicator is involved, or even if this actually happens; I'm just offering an explanation for the phenomenon you say you've observed.)
lemon juice
No colour change, just a very light watery yellow colour that comes out of a lemon.
Dipping blue litmus paper in lemon juice is a chemical change. The acidic nature of lemon juice causes a chemical reaction with the blue litmus paper, turning it red. This change in color indicates a chemical transformation of the litmus paper due to the interaction with the acid in the lemon juice.
what is the initial and final colour of the lemon juice
When lemon juice, which is acidic due to its citric acid content, is mixed with bromothymol blue, the indicator changes color. In acidic conditions, bromothymol blue turns yellow. This color change indicates the presence of acidity in the lemon juice, demonstrating how pH indicators can reveal the acidity or alkalinity of a solution.
the colour of lemons
The color of universal indicator in lemon juice will be red. Universal indicator is a mixture of different pH indicators that change color based on the acidity or alkalinity of a solution. Lemon juice is acidic due to its citric acid content, which will cause the universal indicator to turn red, indicating a low pH level.
