A galvanic cell is compsed of two hydrogen electrodes, one of which is a standard one. In which of the following solutions should the other electrode be immersed to get maximum emf? K_(a)(CH_(3)COOH) = 2 xx 10^(-5) , K_(a)(H_(3)PO_(4)) = 10^(-3) .
In which of the following cells, carbon is not used as positive electrode ?
The EMF of a galvanic cell composed of two hydrogen electrodes is 177 mV . If the solution at one of the electrode has [H^(o+)]=10^(-3) , find the [H^(o+)] at the other electrode.
