Why is a white tile used in an acid - base titration?
It makes it easier to see the colour change in the solution after it reaches its endpoint.
Why indicator is being used in titration?
An indicator is so you can see when the end point of the reaction occurs, or when the reaction is complete. This can be an acid-base indicator such as methyl orange which determines the end point with a colour change.
How is an indicator used to determine the pH of a solution?
Iodine solution is an efficient indicator for starch. It will go from a light brown colour to a black colour if starch is present and will stay light brown if no starch is present. Hope this Helps!
What is the purpose of adding dextrin in titration?
In a precipitate titration, dextrin is added to prevent the precipitate from coagulating during titration. It also makes the color change more visible, since some analytes may be difficult to see a color change during the titration. I hope this helps! This is straight out of my Analytical Lab manual.
What is the Erlmayer Flask used for?
This is a conical flask used for titrations. It has a flat, wide bottom which makes it easier to see colour changes as the liquid from the burette (titrant) is added.

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 do things look a different colour in different light?
You see only reflected light. If the light source changes, then the light that bounces off any object (that you see) must also change.
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.
