Final answer:
Benedict's solution is used to detect the presence of simple sugars like glucose through a color change indicating the reduction of copper(II) ions to copper(I) oxide when the solution is added to the sugar sample and heated.
Step-by-step explanation:
The chemical that can be used to test for the presence of simple sugar is Benedict's solution. When testing for the presence of reducing sugars like glucose, Benedict's solution is the go-to reagent due to its specificity in these tests. The procedure involves adding Benedict's solution to a sample and heating it. A positive result is indicated by a color change to green, yellow, or brick-red, depending on the amount of sugar present. The presence of a reducing sugar, such as glucose, causes the reduction of copper(II) ions to copper(I) oxide, resulting in the color change. It is vital to remember to wear goggles and follow safe laboratory practices when handling Benedict's solution and performing the test.
