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.
The Benedict's test allows us to detect the presence of reducing sugars (sugars with. a free aldehyde or ketone group). All monosaccharides are reducing sugars; they. all have a free reactive carbonyl group. Some disaccharides have exposed. carbonyl groups and are also reducing sugars. Other disaccharides such as. sucrose are non-reducing sugars and will not react with Benedict's solution. Starches are also non-reducing sugars. The copper sulfate (CuSO4) present in. Benedict's solution reacts with electrons from the aldehyde or ketone group of the. reducing sugar to form cuprous oxide (Cu2O), a red-brown precipitate.
