Benedicts solution changes through a range of colours (blue, green, orange, red) according to how much reducing sugar is present in the sample. This can be used to give a rough answer to the question "How much sugar is in the sample?", but is not accurate enough (because of the blending between one colour and the next), to be called a quantitative test.

Benedicts solution
What is the stain solution when chemical is test for sugar?
It is normally benedicts solution. Add about 1/4 of the total sugar solution to a test tube and heat it in a hot water bath at around 50 degrees C for 5 min. For example, heat 40mL of sugar water (C12H22O11 aq ) with 10mL of Benedicts soluton (copper and sodium salts). If it is a positive test it will turn yellow.
