The odor of a smelly shower drain can be eliminated by removing debris from the drain. Discarding the odor-causing material in the garbage outside the home ensures the smell does not invade other areas. Boiling water dissolves oils and grease deposited on the sides of the pipe in the drain, which add to the smell.
Luckily for us, Nernst derived an equation that allows us to determine at what point the two forces (chemical and electrical gradients) balance each other - in other words, at what point we have an ionic equilibrium.
I read about the nernst relation but I can't see why the change in concentration of the electrolyte in the galvanic cell should change the electrode potential,since the ionisation enthalpy and the electron gain enthalpy do not change and hence the tendency of a metal to donate or gain electrons does not change...
