Scale Aluminum

Can you determine the atomic weights of zinc by using?

using chemical reactions?
is this possible?

Electrolysis is used for the production of several important materials on a huge scale. Aluminum, sodium, chlorine, and sodium hydroxide are produced in this way, and copper is purified electrolytically.

Construct an electrolysis cell that consists of a beaker containing an aqueous solution of 0.1 M acetic acid, HC2H3O2, and 0.5 M sodium sulfate, Na2SO4, which is present to conduct electricity through the solution. Immersed in the solution are a strip of zinc metal and one end of a copper wire. The copper wire and zinc electrode are connected through a 1.5 V flashlight battery with the + terminal connected to the zinc electrode. The battery pushes electrons out of its negative terminal toward the submerged end of the copper wire, while the positive terminal of the battery pulls electrons from the zinc electrode. Zinc atoms become oxidized to Zn2+ at the zinc electrode, and the zinc ions dissolve into solution. The zinc electrode is called the anode, the electrode where oxidation occurs. Electrons from the battery move to the Cu wire and react with H+ ions in the solution, reducing them to H2(g). Hydrogen gas rises into the closed end of the graduated cylinder, where it is trapped. The copper wire is called the cathode, the electrode where reduction occurs. The reactions occurring in the cell are thus

Zn(s) ® Zn2+(aq) + 2e- at the anode

2H+(aq) + 2e- ® H2(g) at the cathode

Zn(s) + 2H+(aq) ® Zn2+(aq) + H2(g) overall

The volume of hydrogen gas collected will be studied as a function of the mass of Zn lost from the anode during electrolysis.

While the electrolysis is proceeding, you will carry out a second experiment, in which you will react Zn metal with an excess of strong acid, and collect the hydrogen gas produced. In this case, you will measure the volume of hydrogen gas as a function of the mass of Zn used.
