For the net ionic equations, cancel any substances or ions that appear on both sides of the equation. HCN is a weak electrolyte. On the other hand, HCN is a weak electrolyte which means that at equilibrium, it will still be present in the solution at a significant level. HCN (aq) + KOH (aq) -----------> H2O (l) + KCN (aq) Here the HCN is weak acid, so it will be written in the molecule form. HCN (aq) + OH- (aq) --> H2O (l) + CN- (aq) HCN must be shown as the molecule because it is a weak acid, and so in solution most of it is in the form of HCN. Writing net ionic equtaions is easier than you might think. So the net ionic reaction is given as : HCN (aq) + OH⁻ (aq) ------------> H2O (l) + CN⁻ (aq) The coefficients next to the symbols and formulae of entities are the absolute values of the stoichiometric numbers.The first chemical equation was diagrammed … aus oder wählen Sie 'Einstellungen verwalten', um weitere Informationen zu erhalten und eine Auswahl zu treffen.
