Very excellent! Thank you very much atyy and Borek! My primary concern is solved. Considering the cell as a capacitor, that's what I didn't think about. Even if I thought about it, I still didn't have the "capacitance" to calculate:smile:. Your calculation of the number of ions is...

Thank you, atyy. Some points to your post: 1) As you have stated: So I can infer that the concentration of charge is higher at the vicinity of the cell membrane than in the cytoplasm. Is it right? I don't know what method is used for measuring ion concentration of cells, but I guess it...

We know that cell membranes have a "membrane potential" due to the uneven distribution of dissolved charged particles across the 2 sides of the membrane. So what happen if we withdraw the fluid of just 1 side of a biological membrane? Will we have a solution that is charged?

Thank you Borek, the Nernst equation is perhaps what I am looking for. Indeed I've never heard about solutions containing just a cation, too. I just assumed it.:smile: Perhaps I should describe my idea as: [cation]-[anion]=1 mol/L. I think by biological means we can create a solution like...

Hi everyone, The subject of this topic is what I am looking for. For example if the concentration of a monovalent cation in a solution is 1 mol/L, then how much is the electric potential of this solution? (This solution just contains one kind of monovalent cation and not any anion)...
