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.
The following points should help you to understand how membrane potential works. 1  The difference between the electrical and chemical gradient is important. Electrical Gradient Opposes the chemical gradient. 2  The Nernst equation can help us relate the numerical values of concentration to the electrical gradient.
