Australia is also the only continent that is governed as a single country. It is sometimes informally referred to as an 'island' continent, surrounded by oceans. Our ocean territory is also the third-largest in the world, spanning three oceans and covering around 12 million square kilometres.
Benedict's Reagent is used to detect reducing sugars. What the reagent does is to oxidize aldehydes or alpha hydroxyl ketones. When this happens the color of the reagent turns from blue to colorless by the reduction of copper(II) to Copper(I) that is colorless.
Benedict's test cannot be used to detect the presence of aromatic aldehydes. When Benedict's is used as a chemical test for the presence of reducing sugars in food, the food sample is dissolved in water and about 5ml of the sample solution is added to 5ml of Benedict's qualitative reagent.he colour change is from blue, to brick red. Heat the solution with added benedicts reagent inm a water bath, if the solution changes colour to brick red then a reducing sugar is present. The brick red precipitate is copper oxide, the blue colour of the reagent is copper sulphate. Source(s): jo88 Â· 9 years ago.
