FeCI2 is a combination of iron and hydrochloride. This solution starts out as a yellowish green color. When the equivalence point is reach the solution turns to an orange brown color.

What happens if you overheat a penny during the penny to gold lab?
It changes from the golden color back to a grey color.
What happens if you rub the mineral across a streak plate but the mineral does not leave a streak?
The lack of a streak would indicate that the mineral is harder than the streak plate, or the color of the streak is the same as the color of the streak plate.
What happens to the wave and the color of the wave when you increase or decrease amplitude?
You seem to be talking about a light wave. If you increase the amplitude the light gets brighter, and if you decrease it gets dimmer. Amplitude has no effect on colour.
What happens when you put dye in water?
If you boil it, the water will boil and the dye will not, leaving you with dye.
Is green a warm color cool color or neutral color?
Color green is it warm or cool? it is a hard question if you get to deep into the color but really it is a COOL color.
When is neutralization reached in titration?
Neutralization occurs at the "equivalence point," where the moles of your acid and your base are the same. A chemical indicator tells you when this point is reached, and changes color appropriately.
Why you useindicator in titration?
Most solutions used in titrations are colorless, therefore you cannot really estimate the equivalence point (the volume of added titrant that causes a stoechiometric reaction). However, slight variations in other factors such as acidity (pH) can be detected by means of an indicator, which will change color accordingly. This will notify you when you have reached the equivalence point.
If the equivalence point of a titration is 5 what range of pH should the indicator be?
The indicator should change color right at the equivalence point, so 5.
In a titration when does the indicator change color?
when the equivalence point of a titration is achieved.. Added: (More precisely:) The equivalence point is the point where the number of moles of base equal the number of moles of acid. The end point is the point where the indicator being used changes color (also 'indication point)'. If the indicator is chosen correctly, the end point will essentially be exactly as near as possible at the equivalence point. The point of the titration is to find the equivalence point -- the end point is just a very close approximation to it. This is because the pH of the solution changes very rapidly close to the equivalence point. Therefore, the indicator will change color very close to the equivalence point because of the steepness of the pH change
How does the equivalence point of a titration differ from its end point?
The equivalence point is the point where the number of moles of base equal the number of moles of acid. The end point is the point where the indicator being used changes color (also 'indication point)'. If the indicator is chosen correctly, the end point will essentially be exactly as near as possible at the equivalence point. The point of the titration is to find the equivalence point -- the end point is just a very close approximation to it. This is because the pH of the solution changes very rapidly close to the equivalence point. Therefore, the indicator will change color very close to the equivalence point because of the steepness of the pH change.
How do you know if you reached rocks heart events?
his grey heart color changes
The true equivalence point in these titration was at pH7 What is the pH range for the color change of phenolphthalein?
Phenolphthalein changes from colorless to red in the range of pH = 8.0 to 9.6
Detect equivalence point in titration without an indicator?
Titration without indicator is only possible with another measurement:Examples / possibilities:pH-electrode measurement (acid-base titration)Conductivity measurement (acid-base titration or ion-reaction)Change of color by excess or depletion of the reactant/titrant (redox titration)Precipitation by excess or depletion of the reactant/titrantAdded:(The following was more or less written for 'indicator' titrations, but same principles count for other 'sharply' changing properties):The equivalence point is the point where the number of moles of titrant equal the number of moles of the reactant. The end point is the point where the indicator being used changes color (also 'indication point)'.If the indicator is chosen correctly, the end point will essentially be as near as possible at the equivalence point.The point of the titration is to find the equivalence point -- the end point is just a very close approximation to it. This is because the pH of the solution changes very rapidly close to the equivalence point.Therefore, the indicator will change color very close to the equivalence point because of the steepness of the pH change
When reflection happens is there no change to the color of the light?
the color stays the same
What happens if you mix 1 primary color with a secondary color?
tetriay
What is the difference between end point and equilibrium point in chemistry?
Equivalence point is the point at which the reaction is justcomplete. End point is when there is a permanent color change due to the presence of a indicator.
What happens to m9 paper when?
it changes color
