Lugol's solution is a reagent commonly used to detect the presence of starch. It cannot detect simple sugars because its active ingredient, iodine, does not react with simple sugars like glucose or fructose. Simple sugars do not contain the necessary chemical structure for the iodine in Lugol's solution to form a complex with, so they remain undetected in this test.

What is the difference between a simple solution and dilute solution?
A simple solution refers to a solution where one substance is dissolved in a solvent, usually water, whereas a dilute solution is one in which the amount of solute is low compared to the amount of solvent. In other words, a dilute solution has a lower concentration of solute compared to a simple solution.

Small particles that cannot be removed by simple filtration However they often can be separated through?
Small particles that cannot be removed by simple filtration are typically colloids. These particles can often be separated through techniques such as centrifugation, sedimentation, or using specialized filters like ultrafiltration or dialysis, which can help isolate the colloidal particles from the solution. These methods utilize differences in size, density, or charge to separate the particles effectively.
How do you stop ultrasonic waves?
With a seismograph. While professional seismographs use electronic transducers to detect small movements of a mass, a very simple one can be built with a simple pendulum having a pen attached to it to draw its movements on a sheet of paper.
What is the purpose of compound eyes for grasshoppers?
Compound eyes detect motion, and simple eyes detect light. or The compound eyes are used to "see". The simple eyes are used to detect light intensity.

Why starch reacts with lugols solution?
This solution is used as an indicator test for the presence of starches in organic compounds, with which it reacts by turning a dark-blue/black. Elemental iodine solutions like Lugol's will stain starches due to iodine's interaction with the coil structure of the polysaccharide. Starches include the plant starches amylose and amylopectin and glycogen in animal cells. Lugol's solution will not detect simple sugars such as glucose or fructose. In the pathologic condition amyloidosis, amyloid deposits (i.e., deposits that stain like starch, but are not) can be so abundant that affected organs will also stain grossly positive for the Lugol reaction for starch.
What indicator tests for sugar?
Benedict's solution test can be used to detect the presence of reducing sugars such as glucose, fructose, and lactose in a solution. Benedict's solution changes color from blue to green, yellow, orange, or red in the presence of reducing sugars, depending on the amount present.
How many pages does The Simple Solution to Rubik's Cube have?

What does simple eyes help locust to do?
The simple eye of a locust helps it detect moving objects around it.
How can one detect methanol in alcoholic drinks?
One can detect methanol in alcoholic drinks by using a simple chemical test called the chromic acid test. This test involves mixing a small amount of the drink with a solution of chromic acid and sulfuric acid. If methanol is present, the solution will change color from orange to green. This test can help identify potentially harmful levels of methanol in alcoholic beverages.
