Answer AND Explanation:
Benedict’s Reagent Data
Sample: Initial Color: Final Color: Reducing Sugar Present in Sample? dH2O Clear Blue no
Albumin clear Blue no
Milk white Orange-ish brown yes
Glucose clear red yes
Lugol’s Iodine Data
Sample: Initial Color: Final Color: Starch Present in Sample
dH2O clear orange No
Albumin Clear orange No
Milk White Yellow-ish No
Starch Foggy Black Yes
Raw Potato Yellow Black yes
In each of the two tests (starch and sugar) a positive and negative control was used.Test one positive control was milk and glucose and the negative control was the albumin and dh2o1. Milk and glucose have high levels of sugar present while the others don't.The test two results were positive for potato and starch while the dh20, milk, albumin were negative
In the test for reducing sugars using Benedict's solution, milk and glucose serves as positive controls while distilled water and albumin serves as negative controls.
Benedict's test is a test used to test for the presence of reducing sugars.
A brick-red precipitate using Benedict's test indicates the presence of reducing sugars.
Milk and glucose serves as positive controls for the test because the both contain reducing sugars.
A negative control in Benedict's test will be distilled water and albumin.
This is because neither distilled water nor albumin contains no reducing sugars.
Therefore, milk and glucose serves as positive controls while distilled water and albumin serves as negative controls.
