Warm water and china rose petals itself.....China rose indicator is light pink
light orange/ yellow
Phenolphthalein is clear in a basic solution. As the solution passes the equivalence point (pH=7.00) the indicator will start showing as a light pink in the solution. The lightest pink possible is preferred as your end point, the darker and richer the pink, the farther past the equivalence point you've gone.
Copper Chloride is a light brown colour in its anhydrous (dry) state and if allowed to absorb moisture from the atmosphere turns to a bluey-green coloured dihydrate.
Copper sulphate is a blue coloured solution. As soon as you react it with iron, you will notice that the solution is turning into light green which means iron sulphate solution is forming. Iron being more reactive than copper displaces copper from its soluion.
the light changes colour as some of the wavelengths are absorbed by the coloured glass

Lights are coloured by the light they emit and are additive, while pigments are coloured by the light they absorb/reflect and are subtractive.
what need to do when indicator light is on
Iodine solution reacts with light to undergo a photodecomposition reaction and therefore must be stored in amber bottles to minimise the amount of light that the solution is exposed to. If stored in a clear bottle it will gradually break down as the iodide ions are gradually converted to iodine and the solution turns a yellowish colour.
The third generation iPod shuffle has the indicator light on the top Êclose by the earphone port. This indicator light tells you about the battery charge status.Ê
You see different coloured objects by light. the light hits the object and reflects into your eyes.
Dispersion of light.
We need to know which indicator light you speak of.
