Interpretation:
The Zn+2:Cu+2 concentration ratio should be measured at 250C temperature if the cell potential is 1.16V.
Concept introduction:
The galvanic or voltaic cells are the types of
The cell potential and concentration for the galvanic cells can be determined by using Nernst’s equation which is given as follows:
Where, Q is reaction quotient and known as the ratio of product to the reactant, E is cell potential, E0 is standard cell potential, R is universal gas constant, F is Faraday’s constant and n is number of electrons used.
At, 298K or 250C temperature, the value of R,T and F are put together to obtain a formula as:
Further, a formula used for the standard cell potential is:
