21. To extend the example, let solution A have 30 sodium ions and 30 chloride ions. 22. This is an electrogenic process with an apparent stoichiometry of 3 bicarbonate ions per sodium ion . 23. There are most probably six water molecules in the primary solvation sphere of the sodium ion . 24. They noted there were'problem'sites in the areas occupied by mobile sodium ions . 25. In the reaction between sodium hydrogencarbonate and a dilute acid, the sodium ions do absolutely nothing. 26. This material selectively passes sodium ions while blocking other species, including liquid sodium and liquid sulfur. 27. Sodium ions follow passively through ENaC as a result of the electrochemical gradient caused by chloride flow.28. The influx of extra sodium ions triggers prolonged muscle contractions, which are the hallmark of myotonia. 29. In most vertebrates, sodium ions are the major determinant of the osmolarity of the extracellular fluid. 30. And it's not sodium metal that is dissolved in the blood, but sodium ions .
