Vedclass · Answer

(C) Benedict's solution is a chemical reagent used to test for the presence of reducing sugars,which contain a free aldehyde or ketone group.It contains copper$(II)$ sulfate $(CuSO_4 \cdot 5H_2O)$,sodium carbonate,and sodium citrate.The active species in Benedict's solution is the $Cu^{+2}$ ion,which is complexed with citrate ions to keep it in solution at an alkaline $pH$.During the reaction with a reducing sugar,the aldehyde group is oxidized to a carboxylic acid,and the $Cu^{+2}$ ion is reduced to $Cu^{+1}$ in the form of copper$(I)$ oxide $(Cu_2O)$,which appears as a brick-red precipitate.

Benedict's solution provides which of the following ions?
