What else can I help you with?
Is potato starch a solution?
Starch is not a solution.
What is the organic compound that reacts when iodine is added to starch solution?
The organic compound that reacts with iodine in a starch solution is amylose, which is a polysaccharide and a component of starch. When iodine is added to a starch solution, it forms a blue-black complex with the amylose present in the solution.
What color change does starch indicator solution make in the absence of starch?
Starch indicator solution will remain its original color (usually colorless) in the absence of starch. Without starch present, there will be no color change observed when using starch indicator solution.
What is the name of the major storage compound that is found in the cytoplasm?
Starch. Not in solution, but stored in organelles, amyloplasts.
How indicators works?
pH indicators change their color according to the pH of a solution.
Is potato starch a solution?
Starch is not a solution.
How do you overcome the disadvantages of starch indicator?
All the alpha amylase molecules should rupture . Boil water and then add to the boiling water required starch. Make sure that the starch is alpha and not beta amylase. Use freshly prepared starch solution for iodometric titrations. --unnikrishnan

What are the indicators in iodometry?
Indicators commonly used in iodometry include starch, which forms a blue-black complex with iodine, and potassium iodide, which reacts with iodine to form a yellow-brown color. These indicators help in detecting the endpoint of the iodometric titration.
What does IKI solution test for?
IKI solution is used to test for the presence of starch. Starch will turn blue-black in the presence of IKI solution, indicating a positive test result for the presence of starch.
What chemical is used to test for starch and what is the result if starch is present?
The chemical is called Iodine solution. If starch is present, the iodine solution will turn from amber to blue black.
What color change does starch indicator solution make in the absence of starch?
Starch indicator solution will remain its original color (usually colorless) in the absence of starch. Without starch present, there will be no color change observed when using starch indicator solution.
Which white powder turns blue-black in iodine solution?
Starch powder turns blue-black in iodine solution due to the formation of a starch-iodine complex.
What is the difference between iodine solution and starch solution?
Iodine solution is a brownish liquid used to test for the presence of starch, turning blue-black in the presence of starch. Starch solution, on the other hand, is a clear liquid made by dissolving starch in water.
What is the name of the major storage compound that is found in the cytoplasm?
Starch. Not in solution, but stored in organelles, amyloplasts.
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.
What is acid-base indicators?
These indicators change the color depending on the pH of the solution.
