If you are looking at a iodide to iodine redox titration, the solution would turn yellow instead of blue/black. The blue/black color of the iodine-starch complex is very intense and so the end-point is sharper. Without the starch, the endpoint, when the first yellow from the formation of iodine I2, appears, is less sharp and is harder to see.
What else can I help you with?
Redox titrations of ferrous ion with KMnO4 why the HCl is not used in this reaction?
HCl is not used in redox titrations of ferrous ion with KMnO4 because it can react with KMnO4 and interfere with the titration process. HCl can reduce KMnO4, which would lead to inaccurate results by altering the equivalence point of the titration. Instead, a buffer solution is often used to maintain a constant pH during the titration.
What happen to starch if the saliva was boiled before it is mixed with starch?
Boiling saliva before mixing it with starch would denature the enzymes in saliva that break down starch. This would prevent the starch from being properly digested and broken down into simpler sugars.
What would happen if you did an experiment in which the iodine solution was placed in the Baggie and the starch was in the beaker?
The iodine solution in the baggie would diffuse into the beaker containing the starch. The iodine molecules would interact with the starch molecules, resulting in the formation of a dark blue or black color, indicating the presence of a starch-iodine complex.
What would happen to cells tested with iodine solution?
Cells that contain starch will turn blue-black when tested with iodine solution, indicating the presence of starch. Cells without starch will not change color in the presence of iodine solution. This test is commonly used to identify the presence of starch in cells.
How would the pH of the equivalence point for standard solution titration differ from a strong acid-strong base titration?
The pH at the equivalence point of a strong acid-strong base titration would be 7, as the solution is neutralized. In contrast, the pH at the equivalence point for a standard solution titration would depend on the nature of the reaction and the strengths of the acids and bases involved.

What would happen if the iodine molecules passed through the membrane into the starch suspension?
The starch suspension would form into a blue-black precipitate. This is due to the reaction between starch and iodine.

What would happen if enzyme amylase is absent in saliavary gland secretions?
Starch and glycogen would not be able to be digested and sugar would not be able to be formed.
What would happen if someone forgot to add the starch to the beverage before they began adding iodine?
you die
What would happen if you added water to a starch molecule?
Adding water to a starch molecule would lead to the hydrolysis of the starch molecule into smaller subunits such as glucose. This process involves breaking the glycosidic bonds between the glucose units in starch through the addition of water molecules. Ultimately, this results in the breakdown of the starch molecule into simpler sugar components.
What would happen if you poured starch indicator solution into the cell and filled the beaker with starch and glucose solution?
Well what i think is that The water outside of the "cell" will change colors and not the "cell" :D
What would happen to cells tested with iodine solution?
Cells that contain starch will turn blue-black when tested with iodine solution, indicating the presence of starch. Cells without starch will not change color in the presence of iodine solution. This test is commonly used to identify the presence of starch in cells.
How do you make 100g of glucose?
To make 100g of glucose, you would first need a source of starch, such as corn or potato. You would then hydrolyze the starch using enzymes to break it down into glucose molecules. The resulting glucose solution can be concentrated and purified to obtain the desired 100g quantity.
What would happen if you didn't eat food with any starch in?
Starch is full of carbohydrates, which is your source for energy fast. Not eating a lot of starch will give you a lack of the sugar that is produced from the carbohydrates when broken down for your cells. Pretty much you'll probably feel a little tired.
How would the pH of the equivalence point for standard solution titration differ from a strong acid-strong base titration?
The pH at the equivalence point of a strong acid-strong base titration would be 7, as the solution is neutralized. In contrast, the pH at the equivalence point for a standard solution titration would depend on the nature of the reaction and the strengths of the acids and bases involved.
