It is true some food products labeled as baby carrots are made by cutting down larger roots, and that these items can be treated with chlorine during processing. However, itâs not true thereâs anything wrong with the larger carrots theyâre made from, or that the resultant vegetables reach consumers in a chlorine-soaked state.
The silver is reduced to elemental silver and the copper is oxidized to copper(II): Cu(0) + 2AgNO 3 = Cu(NO 3) 2 + 2Ag(0). The silver crystallizes at the surface of the copper and the copper wire quickly becomes coated with a bunch of elemental silver.
Addition of excess sodium hydroxide solution allows a double displacement reaction, also called a precipitation or metathesis reaction, to occur as the copper (II) ions react with hydroxide ions to produce insoluble, deep blue copper (II) hydroxide (see Equation 2).eaction 4: Formation of Copper(II) Sulfate 1. Add 20 drops of 3.0 M H 2 SO 4 to the solid in the centrifuge tube. Stir carefully to ensure that the copper(II) oxide dissolves completely. Complete dissolution of the mixture will require thorough mixing and possibly heating of the solution.
