There is no silver in a 1964 nickel.
"nickel silver" and "German silver" actually contains no silver, so it is incredibly cheap. It is generally an alloy of nickel, copper and zinc, though the exact formula varies.
None. Alpaca silver is another name for nickel silver which is a base metal alloy of copper with zinc and/or nickel.
US nickels minted from 1866 to mid-1942 and 1946 to the present are made of an alloy of 25% nickel and 75% copper. The weight of a standard nickel is 5.0 gm so that means it contains 1.25 gm of nickel. "Nickels" minted during WWII didn't contain any nickel because it was needed for the war effort. These coins contained 56% copper, 35% silver, and 9% manganese; they're the only US nickels that ever contained any silver.
Those minted in 1964 are 90% pure silver. Those from 1965 to 1970 have a core made of 80% copper and 20% silver, with outer layers that have the opposite percentages for an overall content of 40% silver. All minted after 1970 (except those included in silver proof sets) are copper-nickel and contain no silver. US Mint "Prestige" proof sets include 90% silver Kennedy Halves, although all others versions of the coin including standard proofs are made of copper-nickel.
The voltage of a galvanic cell made with silver and nickel will depend on the specific conditions and concentrations of the electrolytes used. However, the standard electrode potentials for the silver and nickel electrodes are +0.80 V and -0.23 V, respectively. So, under standard conditions, the cell potential would be 1.03 V.
1.05 V
The voltage of a galvanic cell made with silver and nickel will depend on the specific half-reactions involved. However, using standard reduction potentials, the cell voltage can be calculated as the difference between the reduction potentials of the two metals.
The voltage of a galvanic cell made with silver and nickel will depend on the specific conditions of the cell, such as the concentrations of the electrolytes and the temperature. Typically, a cell made with silver and nickel could have a voltage range between 0.8 to 1.0 V.
The voltage of a galvanic cell made with silver (Ag) and nickel (Ni) will depend on the standard reduction potentials of the two metals. The standard reduction potential of silver is +0.80 V and for nickel it is -0.25 V. The voltage of the cell will be determined by the difference in these potentials, so the cell voltage would be (0.80 V) - (-0.25 V) = 1.05 V.
the nickel metal
In a galvanic cell with silver and nickel electrodes, nickel is oxidized at the anode. During oxidation, nickel atoms lose electrons and become Ni2+ ions, contributing to the flow of electrons in the cell. Silver acts as the cathode where reduction reactions take place.
In a galvanic cell made with silver and nickel electrodes, the nickel electrode undergoes oxidation as it loses electrons, which travel through the external circuit to the silver electrode where reduction occurs. This flow of electrons generates an electric current in the cell.
In a galvanic cell with silver and nickel electrodes, the nickel electrode will be oxidized. Oxidation occurs at the anode, where electrons are released as nickel atoms lose electrons and form nickel ions. Silver ions from the other electrode will capture these electrons as the reduction reaction occurs at the cathode.

Yes, a 1946 nickel does contain silver. Nickels minted from 1942-1945 were made with a composition of 35% silver and 56% copper, due to the wartime need for nickel. After 1945, nickel composition returned to the standard 75% copper and 25% nickel.
Galvanic cells containing silver typically involve a silver/silver chloride (Ag/AgCl) electrode as one of the electrodes. These cells work by harnessing the potential difference between the silver and the electrolyte solution to generate electrical energy. Silver galvanic cells are commonly used in medical devices, sensors, and small electronic applications due to their stable voltage output.
