1. Note that the ionic charge determines the sign of the membrane potential contribution. 2. According to the ionic charge is + 3. 3. The manufacturers describe chitosan as an organically inert substance whose molecules have a positive ionic charge . 4. Madison Square Garden buzzed with an ionic charge . 5. When the metal has more than one possible ionic charge or oxidation number the name becomes ambiguous. 6. As the carbon matrix is charged, the charge has to be compensated by ionic charge in the diffuse layer. 7. For simple ions the ionic charge and the oxidation number are identical, but for polyatomic ions they often differ. 8. Because of the risk of ambiguity in allocating oxidation states, IUPAC prefers direct indication of the ionic charge numbers. 9. The collective ionic charge acts to cause the clay plates to repel each other and thus slip and slide against each other. 10. The values calculated with Debye-H�ckel theory diverge more and more from observed values as the concentrations and / or ionic charges increases.
