How do you test for starch?

Answer 1

The most used test for starch is iodine.

Iodine forms a dark-blue complex with starch, at normal temperatures. Usually the iodine is dissolved in a solution of potassium iodide (#K^+I^-#) to form the complex ion #I_3^-#, because iodine doesn't dissolve well in water. Sometimes it's dissolved in alcohol.

Use an iodine solution.

Iodine is an effective tool to test for starch. At normal conditions, it is usually brown, while in the presence of starch, it turns blue-black. See this picture of the test:

To test for starch, you can use iodine solution. When iodine solution is added to a substance containing starch, such as a food sample or a plant leaf, it will turn from brown to blue-black if starch is present.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
