Because the valence of both Cu and Ni is +2, but Ag have a valence of +1 and the metals with lower valence do not form solid solution when added to the metals with higher valence.
Ni(s) | Ni2+(aq) Ag+(aq) | Ag(s)
The addition of Cu to a Ni conductor can improve its mechanical properties and resistance to corrosion. This is because Cu forms solid solution with Ni, enhancing the overall performance of the material. However, excessive amounts of Cu can negatively affect the electrical conductivity of the Ni conductor.
Ni(s) + CuSO4 (aq) --> Cu(s) + NiSO4 (aq) Since nickel appears higher on the activity series of metals table than copper, it replaces copper in a single-replacement reaction. If you perform this reaction in the lab, you shoud see solid copper precipitate out of the solution.
There are four syllables. Ni-ag-a-ra.
In a galvanic cell consisting of silver (Ag) and nickel (Ni), the standard cell potential can be calculated using their standard reduction potentials. The reduction potential for Ag⁺/Ag is +0.80 V, and for Ni²⁺/Ni it is -0.23 V. Therefore, the overall cell potential is approximately +1.03 V (0.80 V - (-0.23 V)). This positive voltage indicates that the galvanic cell can generate electrical energy through the spontaneous redox reaction.

The standard cell notation for a galvanic cell made with silver and nickel can be expressed as: ( \text{Ag} | \text{Ag}^+ || \text{Ni}^{2+} | \text{Ni} ). In this notation, the vertical line "|" represents a phase boundary, while the double vertical line "||" indicates the salt bridge separating the two half-cells. Silver (Ag) is the cathode, where reduction occurs, and nickel (Ni) is the anode, where oxidation takes place.
The reaction between silver (Ag) and nickel chloride (NiCl2) results in the displacement of silver by nickel, forming silver chloride (AgCl) and nickel metal (Ni). The balanced equation for this reaction is: 2Ag + NiCl2 -> 2AgCl + Ni
they are both a metal and a solid
