In EDTA titration, the color changes typically involve a transition metal complex forming with EDTA. For example, in the titration of calcium ions, a color change from red to blue indicates the formation of a complex between EDTA and calcium ions. This color change signals the endpoint of the titration.

Why do you put a white paper under the titration flask?
A white background makes it easier to see color changes in the solution during titration, improving the accuracy of the endpoint determination. It enhances the visibility of subtle color changes, ensuring the titration results are more precise and reliable.
Why is a white tile used in an acid - base titration?
A white tile is used in an acid-base titration to provide a clear background against which to observe the color change of the indicator in the solution being titrated. The white surface helps enhance the visibility of the color change, allowing the endpoint of the titration to be detected more accurately.
How to calculated NaOH concentration be affected if the colour change in the solution is too dark?
If the color change is too dark, it may be difficult to accurately determine the endpoint in a titration. This can result in an overestimation or underestimation of the NaOH concentration. To address this, dilute the solution or use an indicator that changes color at a more suitable endpoint for the titration.
How is an indicator used to determine the pH of a solution?
An indicator is a substance that changes color depending on the pH of a solution. By adding a small amount of indicator to a solution, you can observe the color change and determine the approximate pH based on a color chart that correlates different colors to different pH values.
Why is it that 2 or 3 drops of the indicator is added during titration of acid and base?
Adding a few drops of indicator helps to visually identify the endpoint of the titration, which is the point at which the reaction is complete. The indicator changes color at a specific pH, indicating that the acid and base have been completely neutralized. This helps the titrator know when to stop adding the titrant.

Where and when can one see purple mountains?
Rock mountain.. It changes its colour daily
Who do you see about a mole?
If it looks strange, changes colour, moves around, or does anything abnormal, maybe see your doctor.

What is purple top blood test what does EDTA mean?
Purple Tops are used for full blood counts (CBC test). EDTA is the abbreviation for ethylenediaminetetraacetic acid (you can see why it's abbreviated). The EDTA in purple top tubes is actually usually the potassium salt of this. It's used to keep the blood from coagulating.

What observations tell you that a chemicla reaction has taken place when you cook a burger?
You can see that it changes colour slightly when you cook it and also the fat starts to sizzle out.

Why does the skin change color after exercise?
When you are getting a lot of excersise, your mussels grow bigger, so your skin is more strung and it changes colour because of that. You can see that bodybuilders have a different (often quite weird) skin colour.
Why is starch used as indicator in titration of iodine with sodium thiosulfate?
Starch forms a blue-black complex with iodine, making it easy to see when the iodine has been fully neutralized in the titration. The color change is very distinct, allowing for accurate endpoint determination in the titration process.
Effect of Computer on Human Hair?
Zip, nothing, unless you destatic the screen in where it slightly changes colour and slightly moves. These are too small changes for human eyes or even super-sensitive 3D and HD cameras to see.
