Question

In a galvanic cell, the following cell reactions occurs:

Zn(s) + 2Ag⁺(aq) →Zn²⁺ (aq) + 2Ag(s) 

E°_cell = +1.56 V

(i) Is the direction of flow of electrons from zinc to silver or silver to zinc? 

(ii) How will concentration of Zn²⁺ ions and Ag⁺ ions be affected when the cell functions ?

Answer 1

(i) Zinc to silver

(ii) Concentration of Zn²⁺ ions will increase and Ag⁺ ions will decrease.
