It does have the phosphate ion, but I admit I hadn't thought too greatly about the Ca²⁺∶PO₄²⁻ ratio. But I do realize this is a bit more complex than the Na⁺∶K⁺ ratio because phosphate is used for things such as ATP, NADPH, and to phosphorylate proteins (which is usually considered primarily just for 'signalling,' but an experiment analyzing the subcellular distribution of membrane proteins indicated that the degree of phosphorylation determined the location in relation to the cell membrane; I think this lends support to my idea that protein phosphorylation is also a way to change the isoelectric point of the protein by adding negative charge, thereby changing it's location relative to the mitochondria and cell membrane—these having electric potentials of around −180·mV and −80·mV, respectively.)Why did you choose that form?
