What chemical indicator do you use for starch?
Starch is not the indicator. Iodine is the indicator of starch.
What is the role of an indicator in the titration process?
indicator help us find out which molecules diffused and which didn't for ex: starch indicator indicate starch and glucose indicator indicate glucose.
Which indicator would you use to test starches?
weee
What are the examples of non polar solute?
glucose,fructose,solid iodine,hydrocarbons
Which reacts to iodine glucose or starch?
Starch turns blue when Iodine is introduced. Added: Though it's not quite a chemical reaction, Iodine will give starch a bluish purple color but it stays chemically UNchanged. Iodine stays reddish brown with glucose and many other oligosaccharides (up till about 10 to 15 monomeric glucose units)
What chemical indicator do you use for starch?
Starch is not the indicator. Iodine is the indicator of starch.
What color is glucose when lugol's iodine is added?
I did this lab experiment in my biology class. When Lugol's indicator is added to glucose, it turns to a dark green colour for starch it turns black and for surcose it turns yellow.
What is iodine an indicator for?
Starch.
What is iodine used as an indicator for?
Iodine is used as an indicator for starch. When a substance has iodine added to it, then it will turn into a dark blue color. This is a sign that the substance indeed has starch in it.
What indicator tests for starch?
iodine.
What is the role of the indicator?
indicator help us find out find out which molecules diffused and which didn't.... for example: starch indicator indicate starch......and.......glucose indicator indicate glucose.
How does Lugol's solution work as an indicator?
An indicator is a substance that changes colour in the presence of another substance. Let say inside the beaker are substances of both glucose and starch. The glucose and starch are of same colour. By injecting the lugol's solution into the beaker, the lugol's solution changes colour in the area of where starch is, while no colour changes in the presence of glucose. Thus, by using the Lugol's solution which only acts as indicator for starch and not glucose, we could tell part which area floats around with glucose and starch substances. Lugol's solution works as an indicator because it will stain starches due to iodine's interaction with the coil structure of the polysaccharide.
What is the role of an indicator in the titration process?
indicator help us find out which molecules diffused and which didn't for ex: starch indicator indicate starch and glucose indicator indicate glucose.
How do you make a vitamin c indicator?
Iodine makes a good indicator. The iodine will blend into the surrounding color. Once their is no more vitamin c then the iodine will start to chemically combine with any starches
What chemical detects glucose?
Iodine can detect starch, which is a polymer of glucose
Color of milk after adding iodine?
Starch is not present. Iodine is an indicator for starch.
What will happen if you pour starch indicator solution into the cell and filled the beaker with starch and glucose solution?
The starch indicator solution will diffuse out of the bag (cell) into the beaker, changing the color of the starch solution to a blue, purple, or black color (assuming that it's iodine). The color of the indicator solution inside the bag will not change, because only the glucose can diffuse into the bag, but the starch cannot diffuse into the bag.
