A galvanic (voltaic) cell consists of an electrode composed of nickel in a 1.0 M nickel(II) ion solution and another electrode composed of copper in a 1.0 M copper(I) ion solution, connected by a salt bridge. Calculate the standard potential for this cell at 25 °C .

The standard potential of the cell is 0.77 V

Explanation:

We know that:

The substance having highest positive reduction potential will always get reduced and will undergo reduction reaction.

The half reaction follows:

Oxidation half reaction:

Reduction half reaction:       ( × 2)

To calculate the of the reaction, we use the equation:

Substance getting oxidized always act as anode and the one getting reduced always act as cathode.

Putting values in above equation follows:

Hence, the standard potential of the cell is 0.77 V

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
