Hey Nad! I'm sorry, i dunno the first one... perhaps my earlier post that i gave you would help you again?

The Benedict's test, i think, not so sure but i heard it somewhere...
Ok, i think that the reducing sugars, as they are called, reduce the Benedict's solution. These sugars are like reducing agents, hence their name 'reducing sugars'. In the test the Benedict's solution gets reduced, and the sugars get oxidised. When Benedict's solution is reduced, there is that change in colour.
I hope that i've cleared things a bit.
