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.
Benedictâs or Fehlingâs Reagent is used to test for glucose but not for sucrose. The test involves heating the sugar with either of the chemicals and observing the colour change of blue to orange. This reaction occurs because glucose is a reducing sugar - it can help another chemical to be reduced. Benedictâs or Fehlingâs Regent is used to test for glucose, fructose, maltose and other sugars but not for sucrose. Any sugar mentioned in the examination, which you are not familiar with, should give a positive result for the test. We can summarise the tests for carbohydrate in this table.
