Laboratory #4: Mole Ratios I. Hypothesis: If copper wire is placed in an aqueous solution with silver nitrate‚ then silver crystals will grow on the wire surface and the solution will gradually take on the color of Copper (II) ions. The relative quantities of reactants and products in this chemical reaction can be determined by measuring the mass of copper wire consumed in the reaction and the mass of silver crystals that result. These measurements can then be used to determine the number of moles of
