IIIB. Oxidation reaction with Fehling's solution-(Cu2 /Cu Aldehydes can be further oxidized to carboxylic acids by mild oxidizing agents such as Cu ions. Ketones do not undergo this reaction. One such mild oxidizing reagent is Fehling's solution, a solution of copper sulfate (CuSO4) mixed with an alkaline solution of sodium-potassium tartrate. In the process Cu?+ is...

The following combination of solutions will be added to a medium test tube and observations will be recorded. For each precipitation provide the NET IONIC EQUATION and the FORMULA UNIT EQUATION. If no reaction occurs, write NR (No Reaction). Obtain three medium test tubes and add roughly 5 mL of 0.100 M Cu(NO3). Use (i) as your guide. The exact volume is not important. Then add dropwise each of the following: 1) 0.100 M Na co Write the NIE and...
